To know oneself, one should assert oneself.
Problems are not stop signs, they are guidelines.
Quality is not an act, it is a habit.
Know or listen to those who know.
Be gentle to all and stern with yourself.
Who seeks shall find.
Be thine own palace, or the world's thy jail.
If you can dream it, you can do it.
Expect problems and eat them for breakfast.
If you think you can do it, you can.
Wonder, connected with a principle of rational curiosity, is the source of all knowledge and discover, and it is a principle even of piety but wonder which ends in wonder, and is satisfied with wonder, is the quality of an idiot.
