8 years since I quit full-time employment and went independent! And it has been the best 8 years of my working life! No, it's not about the organizations that I was employed in earlier, but about the sheer freedom to choose what I want to work on and when, not bound by the city's or someone else's time zones.
Of course, this may not fructify when you are at the start your career, and you need to have put in solid work (of being employed) before you can consider going independent. 1/6
