Everybody has problems. I can no more eliminate all problems in this life than a tiger can eliminate his stripes. All I can do is trade one set of problems for another.
I've been homeless and jobless before. Granted, it was for a very short time, and it was mainly by choice, and I've never slept on a park bench or eaten out of a garbage can. But I have tasted it at least, and I'm glad I did.
Think of all the problems you have now. Now think of how many you would still have if you were homeless and jobless. Noisy neighbors? Solved. Being asked to work too much overtime? Solved. Credit card bills piling up? Solved. Car making a funny noise? Solved. Wife won't let you sleep in? Solved.
Add those to the 657 other problems you've got and your life is full of problems. Want to solve them all at once? Easy. Go live under a bridge. Now your problems are gone.
Oh, but guess what? Now you've got new problems. You've simply traded one set of problems for another. So goes the cycle.
The answer, I think, is not to quit your job and live under a bridge. The answer is to deal with your own problems instead of trading them in for new ones. Accept them, embrace them, and then deal with them, as if you were appointed for them.
