There is some self-interest behind every friendship. There is no friendship without self-interests. This is a bitter truth.

When in doubt tell the truth. It will confound your enemies and astound your friends.

The greatest truths are the simplest things in the world, simple as your own existence.

Young people love what is interesting and odd, no matter how true or false it is. More mature minds love what is interesting and odd about truth. Fully mature intellects, finally, love truth, even when it appears plain and simple, boring to the ordinary person; for they have noticed that truth tends to reveal its highest wisdom in the guise of simplicity.

Repetition does not transform a lie into a truth.

This is preeminently the time to speak the truth, the whole truth, frankly and boldly.
