Content is the philosopher's stone, that turns all it touches into gold

I have never seen the Philosopher's Stone that turns lead into Gold, but I have known the pursuit of it turn a Man's Gold into Lead.

Get what you can, and what you get hold, 'Tis the stone that will turn all your lead into gold

If you know how to spend less than you get, you have the Philosophers-Stone

Content makes poor men rich; discontentment makes rich men poor.

Content and Riches seldom meet together, Riches take thou, contentment I had rather.
