I can, therefore I am.

Do not weep do not wax indignant. Understand.

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

Problems are not stop signs, they are guidelines.

Quality is not an act, it is a habit.

Things do not happen. Things are made to happen.

Never complain and never explain.

Begin to be now what you will be hereafter.

Know or listen to those who know.
