It is a difficult choice people have to make, choosing a career that either benefits society at large, or just themselves and their families. I haven't worked for anyone for 15 years, and I am probably unemployable at this point.
We consume way too many things we don't need. I've been scaling back, and this year I plan to sell the majority of things I don't use or need, or simply give them away to those who could use them.
The best time to start a business, even on the side, is right now. I start my one company in 2009, and within a year, I quit my job and it's been my daily interest ever since.
