Never complain and never explain.

It's always too early to quit.

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

After a storm comes a calm.

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

Quality is not an act, it is a habit.

If you're going through hell, keep going.

What you do today can improve all your tomorrows.

To know oneself, one should assert oneself.
