Straight: Average Joe, who works at a Burger Fool job, travels into the future and discovers that in just four years, he will be vice president of the national corporation that owns the chain. And is married to a supermodel.
Exaggerated: Joe travels four years into the future and discovers that his future self is king of the world.
Downplayed: Average Joe, who works at a Burger Fool job, travels into the future and discovers that in four years, he will be promoted to the manager of the restaraunt he was working at, after his four years of dedicated work is finally recognized.
Joe's future self got rich by using Time Travel for Fun and Profit, the with the same method of Time Travel that his present self was using. With a copy of The Wall Street Journal for next week, he knew which stocks to invest in.
Alternately, current!Joe already put all the events in motion that led to future!Joe's success; all he's seeing is how those plans turned out.
Subverted: Future Joe talks with Present Joe and claims to be extremely successful. But for whatever reason, he was lying.
Double Subverted: The future self at first appears to be a highly successful doctor. This turns out to be a fake. However...the reason for the fake was that he is a highly successful FBI agent busting a scheme to harvest people's organs without their consent.
Present Joe gets drunk for the first time, and passes out in a ditch. Then he falls asleep and dreams about a highly successful future for himself. This successful future reminisces about how "The last mistake I ever made was that day, four years ago, when I got drunk and passed out . Ever since then, everything I've ever done has been successful, so here I am, with everything I ever wanted."
Alice, Bob, and Joe travel into the future, and they are naive enough to think that all of them will be some kind of overnight success. In actuality, they find that Joe is Ridiculously Successful, Bob is a Future Loser (much more of a loser than in the present), and Alice is just as average as she is in the present.
Four years in the future, Joe is ridiculously successful. But he also travels forward eight years, and finds that all his success in Year Four has been undone. Joe-from-eight-years-in-the future is no more successful than you would expect from the character traits and cirumstances of Present-Day!Joe.
Averted: Pretty much any life path but extreme success. Or no time travel at all, or there is time travel but it doesn't involve finding any knowledge about the main characters' future selves.
Enforced: The writer had wish fulfillment as his motive for writing his story, just as this is his readers' motive for reading it.
Discussed: "I can't wait to see my own future as a rich rock star!"
Conversed: "Why do you watch this show? Oooh, this loser becomes a millionaire! But instead of thinking up a plausible reason for this to happen, they just sent him four years into the future and said that every event in his life made him become rich! Well, I suppose I shouldn't be taking it so seriously."
Deconstructed: Joe travels into the future, finds that his future self is ridiculously successful, and given the way time travel works in this fictional Verse, Joe has the option of just staying in the future and enjoying his future self's success, without having to work for it. However, he ends by learning the Aesop that he can't be truly successful if he shortcuts his way out of having to do the character-building and skill-building that made his future self successful.
Reconstructed: The future self gives a character-building explanation: the same Aesop above. This Aesop is, in fact, the reason why he was able to grow as a person and become this successful in the first place.
