Be gentle to all and stern with yourself.

It's always too early to quit.

The wise does at once what the fool does at last.

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

Well done is better than well said.

By failing to prepare, you are preparing to fail.

What you do today can improve all your tomorrows.

Never complain and never explain.

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