My experience with freelancing mirrors this. It is a bit more stressful because I'm actually working much more efficiently and seriously but I earn twice as much and I can choose my own schedule...

It's liberating. In my old job, I was frustrated and not as happy... now I've got more money, do some really fun projects (because when freelancing you do get to pick your clients a bit more) and I'm trying to grow bigger so as to launch my own product... Life is good...

So to anyone frustrated with his work, I would definitely recommend trying to freelance...
