I've been full-time for about a year. I worked part-time for about 3 years as a hobby and for the extra cash. When my income had grown enough to cover my day job's salary... that's when I quit. It was perfect timing too. I had neglected my responsiblities at my regular job and I was about to get fired anyway. I worked in sales and most of my day was spent out of the office. I would go home and work on my websites. Lol. I think I was actually more productive when it was a hobby.
