I was a school network tech making $36k, working 35 hours a week, easy job, but i completely hated the f'ing environment. I quit, even though the woman and family all gave me shit for it. Now I make more money (about 50% more, my first year in business), I work less hours, I post on getbig all day, and the only little rugrat I see all day is my own.
Go with your heart. If you're not a lazy bastard, money will always come to you for your work. And avoid dying industries.
