Even a bit later, sometimes. From "Snow Crash":

Until a man is twenty-five, he still thinks, every so often, that under the right circumstances he could be the baddest motherfucker in the world. If I moved to a martial arts monastery in China and studied real hard for ten years. If my family was wiped out by Columbian drug dealers and I swore myself to revenge. If I got a fatal disease, had one year to live, devoted it to wiping out street crime. If I just dropped out and devoted my life to being bad.

Hiro used to feel that way, too, but then he ran into Raven. In a way, this is liberating. He no longer has to worry about trying to be the baddest motherfucker in the world. That position is taken.
