Don't imagine that you'll discover {the truth} by accumulating more knowledge. Knowledge creates doubt, and doubt makes you ravenous for more knowledge. You can't get full eating this way.
Stop thinking, and end your problems.
Do your work, then step back. The only path to serenity.
He who tip-toes cannot stand; he who strides cannot walk.
Governing a great nation is like cooking a small fish, too much handling will spoil it.
The words of truth are always paradoxical.
