To know oneself, one should assert oneself.

It's always too early to quit.

Quality is not an act, it is a habit.

Always desire to learn something useful.

To be a good loser is to learn how to win.

By failing to prepare, you are preparing to fail.

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

Leap, and the net will appear.

What you do today can improve all your tomorrows.
