Never complain and never explain.

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

Quality is not an act, it is a habit.

It's always too early to quit.

Problems are not stop signs, they are guidelines.

The secret of getting ahead is getting started.

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

You never know what motivates you.

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