Dude, you've gotta give it a try. I lived the cubicle/office nightmare for 10 years after college (approximately 9 1/2 yrs too long). I was 32 before I had the balls to drop everything and go flying.
Three years later I'm in the right seat of a regional jet, hopefully on the way to a decent flying career. I make about 1/4 what I made before and haven't regretted my decision for one second.
Do it now before you do something irrational like get married or have kids
