Read "Kitchen Confidential" by Anthony Bourdain and then decide if you want to follow that career path.
Bourdain's certainly not a role model, and I don't know that I'd go to him for advice

I work with a guy who spent many years working in high end restaurants in the DC area, and he says Bourdain fairly accurately portrayed what it was like to work in that line of work. He's the one who got me to read that book.

My friend's point was that he spent most of his nights cranking out the two menu items he was responsible for. Over and over and over.

He's a technology planner with a regular day job these days ...
