Stumbled upon the 101 reasons why freelancers do it better, in particular I liked this valuable points:
Rewards are immediate: Freelancers don’t toil away for 20 years just to be presented with a gold watch and a pat on the back. Instead, they get work, bonuses and positive networking that’s worth infinitely more.
Pushing yourself pays off: Your growth is only limited by your imagination and effort.
Your motivation is based on production, not a time clock: If you finish work faster than you were supposed to, you won’t have to kill time until 5 p.m.; when you’re done for the day, you can actually be done.
