But if it's really good, you're gonna need a bigger room.
And when you're in the bigger room you might not know what to do.
You might have to think of how you got started: sitting in your little room."
A character becomes successful in an activity, promptly lets success go to their head, and then loses the drive that made them successful in the first place.
Say Bob is a talented singer/songwriter. He got it from years of practice and determination and eventually gets noticed for it. He gets a cushy contract, and women are all over him. Soon he loses the determination to make good songs, and only cares about the money and the prestige, rejecting the idea of Doing It for the Art even when he can afford to do potentially unprofitable side projects.
What happens then can vary. He might become a Jerkass to his friends or a jerk to everyone else. He might start losing his skill and have to take drugs just to get on stage. He might lose his contract and his money, and either learn an Aesop or spend the rest of his life moping about his Glory Days. He might even keep all those, and get a job as a music executive where he's totally cynical to anyone new who thinks this is "just about the music".
This can make up entire plots, or just make a backstory for some character who is either the cynic or lost it all. Often happens in a Sitcom, sort of overlapping with Compressed Vice. In this case, losing it all is how the Reset Button is pressed. This can be Truth in Television, although many times it's hard to tell, as it's often fans complaining of Sell-Out and It's Popular, Now It Sucks!.
Compare/Contrast I Coulda Been a Contender!.
- Mokoyama from Yakitate!! Japan got this way when he was hired by St. Pierre, becoming more interested in luxury and makeovers than baking.
- In Dragon Ball Z, Videl explains that after Mr. Satan became world-famous, he got so caught up in the money, prestige, and women that he stopped training. Gohan sensed that Videl was already stronger and more skilled in martial arts than Mr. Satan.
- Tiger Mask proposes an interesting variant: at one point Tiger Mask did stop training beyond the bare minimum and lost his edge, but it was because the reason he was fighting, namely paying the bills for the orphanage where he grew up, before Tiger's Cave, got him caught in a series of matches for his NWA Maskmen World Champion belt and just didn't have time to train, and by the time he got to the eighth and last challenger, Tiger's Cave wrestler Miracle 3, he wasn't at his best anymore, and once his Fujiyama Tiger Breaker failed he couldn't fight back effectively and lost. Winning backfired horribly on Miracle 3, as losing gave Tiger Mask the time to train himself back into shape (becoming a match for Miracle 3) and devise the Tiger V (that Miracle 3, not having seen before, could not counter), leading to Miracle 3's defeat and unmasking as a fraud.
- 18if: Mirei Saegusa attempts to cut off her leg as an attempt to abandon ice-skating because of this trope. She felt the constant pressure from sponsors, fans, and trainers taking the fun out of ice-skating.

Zola later admits Cezanne is right, but Zola finds his passion again when he stands up for the wrongly imprisoned Alfred Dreyfus.
- A theme in Rocky III is that Rocky Balboa got so caught up in the fame and money that he lost his edge. His rival Clubber Lang paints himself as the hungry new star and Rocky of being a "paper champion" living on past glory. Heck, the theme for the movie even includes the trope name.

- The main theme of The Candidate. Bill McKay is an idealistic liberal crusader recruited for a Senate campaign that neither he nor his campaign manager thinks he has any chance of winning—the idea is that simply by running, Bill will raise awareness of his liberal causes. However, as the campaign unfolds, it turns out that Bill does have a chance to win. Faced with the chance to actually be a senator, Bill rapidly starts making compromises and selling out his principles. In the end, he wins but he's sold his soul and has no idea what to do.

Serge is only still around so he can rise up the chain of command and be an Internal Reformist. He kicks off the plot and answers the request Ella's late mother submitted on a spur of inspiration to do the job he loves again.
- Played with in the second season of Extras. The main character, Andy, gets his own sitcom which makes him ridiculously famous...but the show has been meddled with so much that it's no longer any good in Andy's opinion (and in the opinion of LOTS of other people.) Andy struggles with continuing to do the show and being a rich laughingstock or quitting the show (and permanently damaging his career) to do better work.

You must fight just to keep them alive."

- Many stories in the WWF/WWE highlight this trope as the frequent downfall of heels (and occasionally faces) who have been champions for long periods of time. Eventually, a combination of arrogance and complacency lands them a defeat at the hands of their title-hungry rival.
- Stone Cold's infamous FaceHeel Turn had him ally with Arch-Enemy Vince McMahon to claim the title at Wrestlemania 17. However, Austin's main drive was largely to torment and harass Vince and his allies. His Badass Decay got to the point where Vince himself was actively trying to provoke him into attacking him so he'd snap out of it. Fittingly Austin did eventually return to his old self by screwing Vince and the entire WWF - by handing a win to WCW, no less.
- CM Punk accused John Cena, in his hometown of Boston no less, of having sold-out his ideals and no longer being the plucky underdog he portrayed himself as.

- Ace Hardlight in Ratchet: Deadlocked was once a genuine hero but fell into a depression after a mission gone awry resulted in the destruction of his home.

- The protagonists of Persona 5 initially start their escapades to protect themselves and others from the "assholes" in power that abuse the weak. Once they realize that Mementos is unlocked as the Phantom Thieves get more ingrained in the public consciousness, they also try to go after high profile targets to raise public support for their mission of social change. However, they start to buy into their own hype around the time they "defeat" Medjed, and their goals shift from social reform to popularity, making them more of a fad than true reformers. It turns out this was all part of a Batman Gambit by Masayoshi Shido and The Conspiracy to discredit the Phantom Thieves by framing them for murder after their target dies on TV. Though the Phantom Thieves were set up and didn't actually kill anyone, the public thinks they did, and support for the Phantom Thieves plummets. This can also happen permanently in the final bad ending, wherein Joker abandons his principles and sides with Yaldabaoth, the totalitarian God who's been manipulating everyone behind the scenes.
- This is one of the major themes of Saints Row: The Third. The Saints have become just as much of a media empire as a gang, and they've grown soft as a result, allowing The Syndicate to nearly take them out.

Canonically, they go right back to their old ways after defeating STAG and running the Syndicate out of town, selling out for glory and fame, culminating in a term in the White House as President by the next game.

- It's implied that David Xanatos in Gargoyles worries about this, since he's built himself up from nothing to have immense wealth and power but now there isn't much left for him to aspire to. Part of what he gets out of his fights with the gargoyles is that they let him prove that he's "still got the edge."
