I got fed up of this at 40, mid life crisis... i had been working like this for 12 years... had enough savings to last 2 years. I quit then reflected for 2 months on what i was good at and enjoyed, tried it, it worked a bit, found somthing else, it worked too. 6 month later, got my first check . 1 year later was earning more than my previous job and was a free man doing two activities i adore. 4 years now and my 1-man company is healthy. What it took: courage to make the big jump in the unknown... it was scary, but exhilirating at the same time. Definitely worth it, i am so much more alive in my forties than i was in my thirties!
