Each person is different and has a different set of circumstances. Myself, I have no wife, kids are grown and no bills.
Bandit is also single but spends tons of money on women, concerts and booze.
Some people say they make $70,000 but after paying for child support and truck payment they are lucky to make $30,000 and on top of that can't even afford a place of their own so, it's all relative.
And yes, I gave up a 6 figure salary to do this. I've found that being happy is so much more important then money.
