To know oneself, one should assert oneself.
Problems are not stop signs, they are guidelines.
Never complain and never explain.
Expect problems and eat them for breakfast.
Be gentle to all and stern with yourself.
It's always too early to quit.
Be thine own palace, or the world's thy jail.
Well done is better than well said.
Always desire to learn something useful.
What you do today can improve all your tomorrows.
I'm not a bad driver. And I never will be because I took lessons when I was quite a boy. I never had to pass a test because there wasn't such a thing when I first started driving a motor car. So I didn't have to pass one.
