No cure, no pay

Every sun has to set

Every day of your life is a page of your history.

Believe what you see and lay aside what you hear.

Ask the experienced rather than the learned.

A known mistake is better than an unknown truth.

A change is as good as a rest

A chameleon does not leave one tree until he is sure of another.

Write the bad things that are done to you in sand, but write the good things that happen to you on a piece of marble.
