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.

- The Stand: Played completely straight with the musician Larry Underwood, although he eventually stops acting that way.
- This is Serge the Fairy Godfather's personal conflict in Disenchanted: The Trials of Cinderella.

- 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.

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.
