I can, therefore I am.

Be gentle to all and stern with yourself.

Be kind whenever possible. It is always possible.

Do not weep do not wax indignant. Understand.

The secret of getting ahead is getting started.

Be thine own palace, or the world's thy jail.

Know or listen to those who know.

The dog that trots about finds a bone.

Things do not happen. Things are made to happen.
