Aesop

The injuries we do and those we suffer are seldom weighed in the same scales.

Our insignificance is often the cause of our safety.

Every truth has two sides; it is as well to look at both, before we commit ourselves to either.

Power is not only what you have but what the enemy thinks you have.

All those who offer an opinion on any doubtful point should first clear their minds of every sentiment of dislike, friendship, anger or pity.

It's good to like yourself, and that only comes from hard work, from doing. But vanity is dangerous; it can trip you badly.
