I can, therefore I am.

The dog that trots about finds a bone.

Do not weep do not wax indignant. Understand.

If you think you can do it, you can.

The wise does at once what the fool does at last.

Things do not happen. Things are made to happen.

Know or listen to those who know.

You never know what motivates you.

Expect problems and eat them for breakfast.
