To know oneself, one should assert oneself.
Never complain and never explain.
You never know what motivates you.
Be gentle to all and stern with yourself.
Who seeks shall find.
If you can dream it, you can do it.
Be kind whenever possible. It is always possible.
If you think you can do it, you can.
Be thine own palace, or the world's thy jail.
Expect problems and eat them for breakfast.
It is no use painting the foot of the tree white, the strength of the bark cries out from beneath the paint.
