Fist thing you can ever hope to achieve by writing stuff is confidence. The better the stuff you write is, the more confidence you're gonna get. Chicks like that, too—confidence, self-respect, self-esteem, all that nonsense—but you can't fake it. However you get it, that's what you want. If money gives you confidence, make lots of money. If writing good stuff gives you confidence, write good stuff. If writing shit that appeals to the demographic some marketing guy determines will buy gives you confidence, write that crap.
You're a young guy, what you wanna write might just totally fit the right niche. Write it and see, that's what I say. Does that answer your question? G.
