I can, therefore I am.

To know oneself, one should assert oneself.

If you can dream it, you can do it.

Things do not happen. Things are made to happen.

The dog that trots about finds a bone.

Do not weep do not wax indignant. Understand.

What you do today can improve all your tomorrows.

Know or listen to those who know.

It's always too early to quit.
