Francois de La Rochefoucauld

People have this idea that the more pious and devout I am, the more successful I am. Which is very dangerous. If you look at faith in that way, you're bound to fail at both - spiritually and in your career.

Resolve not to be poor: whatever you have, spend less. Poverty is a great enemy to human happiness; it certainly destroys liberty, and it makes some virtues impracticable, and others extremely difficult.
