Your shy friend should be forced into terrifying things, or completely changing themselves, and you're an awesome person for dragging them into a life-threatening situation without any sort of consent. And if they turn into a complete bitch because of the stress, it's totally their fault or the person trying to help them improve their lives; not you.
Meta example: An attempt at making an engaging cartoon for little girls will end up attracting primarily adult men.
Throwing temper tantrums and dishing out personal attacks is a great way to show that you appreciate your show.
It doesn't matter if the performance is free, the attendance optional and everyone else seems to be enjoying themselves. If you don't like it, heckle and try to upstage the performer instead of just leaving. If they put you in your place, they're the ones in the wrong.
There will be minimal negative ramifications, for you, for heading into an Eldritch Location to lure an uncontrolled giant monster, say, a celestial ursine to your populated and unsuspecting village for something as petty as finding out if someone has accomplished a feat before, on the grounds of if they could do it before, regardless of possible unknown circumstances involved, she can do it again. And if she can't, well the safety of you and your neighbors is someone else's problem.
The appropriate punishment for such property-damaging and life-threatening stupidity is to give the offenders mustaches.
Being a jerkass and a braggart means that you deserve to have your life and possessions destroyed.
It's completely fine to laugh at the misfortune of others if you're the protagonist.
If you see a problem imminent that nobody else does, it's perfectly okay to not even bother informing anybody of it beforehand; instead, start preparing to fix the resultant disaster yourself, singlehandedly, and you will win praise and admiration from people who'll completely ignore that you could have stopped this before anyone went wrong.
If you don't seem to be good at anything, go into management! (Just like in Dilbert!)
The plebeians cannot manage themselves and require the nobility to organize them into being effective at their tasks.
If you fail at real work because you're too accustomed to using resources inherited from your noble bloodline, it's not because you're spoiled, it's because you're naturally gifted in being in a position of authority.
Always stick with your traditional ways, even if those ways mean you fail in your annual task each and every time.
Allowing two races to work at optimum efficiency while forcing a third one to ignore their natural talent (of having a magical horn) is not racism, it's tradition.
If you let rivalry interfere with your performance in a race, you'll lose to the nonathletic nerd.
You can be crowned winner of a sporting event if you use a blatantly unfair advantage against an opponent you couldn't beat without said advantage. You keep the winner's title anyway, and no one besides the loser will question it.
Alternatively, using your natural talents is absolutely wrong. You must always bring yourself down to other people's level.
Some people are inherently more advantaged than others.
If you go insane over some silly detail, it's your friends' fault for not taking your baseless, self-imposed, and idiotic freakout seriously enough.
Brainwashing an entire town pales in comparison to ignoring a friend or being a bad student. Seriously, it's not like your selfish and ethically ropey misuse of magic was heinous, creepy, or downright dangerous, or anything like that.
Technological progress and men in management positions are evil! Oh, and so is capitalism. If two guys show up with a perfectly effective means of fostering industrialization and increasing overall productivity, it's your duty to humiliate them and permanently run them out of town, even if they're technically just doing their jobs.
Oh, and that applies even if they're only filling an economic niche you can't due to inadequate production. Free market competition is bad, kids!
Gamble your livelihood recklessly; even if you lose, events will conspire to help you get back into business anyway.
Singing traveling salesmen are evil. If any show up, destroy them.
Stalking, harassment and accidental vandalism will make you friends.
Unfriendly people are really just hiding their inner pain. Pester them until they reveal it to you.
Being friends with people is a thing you must do because you always make friends with people and this one will be no exception! It's not because you genuinely have their best interests at heart, or anything like that. You just want to prod them until they do what you want them to do.
Putting a note in an awkward place, or not looking for one, is romantically tragic rather than pretty stupid.
Everyone has to like you and be your friend. If someone doesn't want to be friends with you, something is definitely wrong with him or her.
Just give in and let your friend finish your test for you, surely your teacher won't mind.
Completing a test given by a Princess - who doesn't even have the decency to explain what it is beforehand - is clearly so important when the stakes are hundreds of innocent lives. This is why it's OK to worry about the test even when an entire empire is being consumed while you waste time thinking about it.
The best way to reward someone for saving your life is to not invite them to your empire, but invite all of their friends (who did nothing) instead.
Don't ever take your kids to Equestria. If they're bullied, no one will even notice, much less lift a hoof to help them.
Just stand there and watch when your younger sibling is being bullied, they'll sort it out themselves.
An apologetic bully gets no punishment, no matter how nasty she's been, so long as she has a sympathetic enough sob story which isn't too different from the sob story of her victims (i.e. getting bullied for their lack of something).
Your bully will be your best friend if you save them from the trap that you originally built to humiliate them completely.
If you have a Freudian Excuse for your bad actions, everybody will forgive you easily.
Bullies are just covering up their own insecurities and should be treated with kindness, except when they shouldn't.
If you attempt to get revenge on a bully, you're the bad guy, not the bully.
Recklessly endangering the life of your bully isn't a major overreaction to being bullied.
Warping the warp: Throwing food at your victims, stalking and tormenting your victims, and destroying their property aren't cruel actions of bullying. Especially if you have a Freudian Excuse.
Missing the point warping: Potentially murdering your bully is a perfectly valid response to being bullied.
If you don't forgive your bully, something's wrong with you.
Your victims of your bullying will forgive you easily, no matter how bad you treated them. They won't be traumatized or hold a grudge against you for it, not at all!
All schoolyard bullies deserve sympathy if they have a tragic backstory, despite the fact that they threw food at you, destroyed your property, stalked you and humiliated you every chance they got. Victims who don't forgive their bullies easily are just jerks.
When you realize just how horrible things you were doing in order to get a revenge on your unwilling rival, you should seek her forgiveness. But feel free to ignore all those other people you've been tormenting along the way.
Don't bother trying to improve yourself. You'll only turn evil.
If someone tells you something you're trying to buy is dangerous, then meh, someone will come and save you later, and you can just say sorry. That gives you instant amnesty.
You can spend your money to buy victory.
Not to mention cheat your way to it too. But don't worry, it's completely justified if your friends are part of the whole thing.
Torturing children, enslaving an entire town, and downright being mean is no big deal if you apologize afterwards.
If you actually expect money in return for watching over a pet and aren't just doing it out of the kindness of your heart you're being a greedy, careless bastard.
The universe will hate you, even if you did a good thing and saved a lot of people.
Of course you're frustrated that you weren't invited back to an empire you helped to save from the clutches of evil, and one of your friends completely understands how you feel. You're still not going, though. No one else cares.
Brainwashing your enemies to join on your side is morally ok, as long as you or your leader have a "good use" for him.
An unapologetic sociopath is damaging your home and threatening to drive a wedge between you and your best friends? The only solution is to put all your trust in friendship being enough to change him. If he still takes actions that hurt you or others, you're not being friendly enough.
The best way to attract people to your town is to get a group of people from another town far away who've only visited once before to do it for you.
If your visitor turns out to dislike fancy fanfares, but nevertheless is annoyed at not getting any kind of welcome at all, she'll be perfectly happy upon hearing that there was a fancy fanfare (but it was accidentally given to somepony else), so happy ending. Yeah, us neither.
If you`re not sure how something works, the best way to find out is by ignoring vague warnings and using it. And if you can fix whatever problems your curiosity creates, your ingenuity will be rewarded, giving you even more power and responsibility.
Accidentally mind-raping your friends is sure to work out in your favor!
Your destiny is EXACTLY one vague interpretation of a picture on your butt, and there's no variation. That includes the smiling flowers meaning you should be a teacher.
If you hate what you do for a living, but are told it is your destiny, don't question it and don't try to find something else you enjoy.
If you have a tattoo of something tangentially related to a job on your thigh, it is clearly your destiny, regardless of how completely incompetent you are at it.
It's not okay to mess with the lives of others... unless you're a god.
"Destiny" and "creating a new magic" both make good qualifications for being promoted to what seems to be a leadership role. Oh, all that aptitude stuff about your mental instability, tendency to freak out, semi-reclusive nature, and most recent incident involving reckless use of unknown magic? And the possibility that one of your friends has learned just as much about this magic as you have? Or that little thing called the consent of the pony who's apparently having this destiny handed to her so suddenly and unexpectedly? It doesn't matter at all.
Only royalty deserve to be members of the Alicorn master race. The plebeians all have to get by stuck on the ground without opposable thumbs, much less magic, to interact with the world.
Most of your leaders are missing and you only have one left to rule the land if you fail your potentially suicidal mission? Don't send her away to look after the town, bring her with you! If you really think a person in a position of high authority shouldn't be out on the front lines, you're just not a very good friend.
Your friend is the only one who knows what your goal even looks like, has the knowledge and skills to fix the problem, wears a key to making your superweapon work, and can not only fly or teleport out of danger but has more power than all of you combined? Never mind all those times you learned to stick together: send her away, because she'll only be a liability.
