What makes art in general, and literature in particular, remarkable, what distinguishes them from life, is precisely that they abhor repetition. In everyday life, you can tell the same joke thrice and, thrice getting a laugh, become the life of the party. In art, though, this sort of conduct is called 'cliche.'
I've never forgotten what it's like to be in your early twenties, which is not a particularly easy time. You've left your family, you've left the strictures of high school, and you're trying to break free and form yourself but you have to support yourself as well. We don't really give enough credence to that time of life and to its troubles.
