You should avoid making yourself too clear even in your explanations.
There is none who cannot teach somebody something, and there is none so excellent but he is excelled.
Many have had their greatness made for them by their enemies.
The greatest fool is he who thinks he is not one and all others are.
Every fool stands convinced; and everyone convinced is a fool. The faultier a person's judgement the firmer their convictions.
Honorable beginnings should serve to awaken curiosity, not to heighten people's expectations. We are much better off when reality surpasses our expectations, and something turns out better than we thought it would.
