Know or listen to those who know.

Things do not happen. Things are made to happen.

The dog that trots about finds a bone.

Always desire to learn something useful.

The most effective way to do it, is to do it.

Do not weep do not wax indignant. Understand.

I can, therefore I am.

To know oneself, one should assert oneself.

Quality is not an act, it is a habit.
