Never complain and never explain.

To know oneself, one should assert oneself.

You never know what motivates you.

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

What you do today can improve all your tomorrows.

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

Quality is not an act, it is a habit.

After a storm comes a calm.

By failing to prepare, you are preparing to fail.
