Never complain and never explain.

If you're going through hell, keep going.

If you think you can do it, you can.

Be gentle to all and stern with yourself.

What you do today can improve all your tomorrows.

Go for it now. The future is promised to no one.

If you've got a talent, protect it.

To know oneself, one should assert oneself.

Well done is better than well said.
