To know oneself, one should assert oneself.

I can, therefore I am.

What you do today can improve all your tomorrows.

Quality is not an act, it is a habit.

Know or listen to those who know.

The dog that trots about finds a bone.

The secret of getting ahead is getting started.

By failing to prepare, you are preparing to fail.

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