Never complain and never explain.

Be thine own palace, or the world's thy jail.

The dog that trots about finds a bone.

To know oneself, one should assert oneself.

If you think you can do it, you can.

What you do today can improve all your tomorrows.

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

It's always too early to quit.

Well done is better than well said.
