There will be sleeping enough in the grave.

Dost thou love life? Then do not squander time, for that is the stuff life is made of.

I think also, that general virtue is more probably to be expected and obtained from the education of youth, than from exhortations of adult persons; bad habits and vices of the mind being, like diseases of the body, more easily prevented than cured.

If you can't pay for a thing, don't buy it. If you can't get paid for it, don't sell it. Do this, and you will have calm and drowsy nights, with all of the good business you have now and none of the bad. If you have time, don't wait for time.

Human happiness comes not from infrequent pieces of good fortune, but from the small improvements to daily life.
