To know oneself, one should assert oneself.
Things do not happen. Things are made to happen.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
Quality is not an act, it is a habit.
Wherever you are - be all there.
Never complain and never explain.
If you're going through hell, keep going.
Problems are not stop signs, they are guidelines.
If you think you can do it, you can.
My definition of courage is never letting anyone define you.
