You can be invincible, if you enter into no contest in which it is not in your power to conquer.

There is no such thing as defeat in non-violence.

Never confuse a single defeat with a final defeat.

I never wanted to experience the still-familiar feeling of defeat again.

Never pick a fight with someone you're not sure you can defeat.

Success is never accidental.

Never attempt to win by force what can be won by deception.

Never compete with someone who has nothing to lose.

If you prepare properly, you may be outscored but you will never lose.

You are invincible if nothing outside the will can disconcert you.

Never fear another challenger, no matter how large; Never despise another challenger, no matter how small

If you opt for a safe life, you will never know what it's like to win.

you ought never to suffer your designs to be crossed in order to avoid war, since war is not so to be avoided, but is only deferred to your disadvantage.

For men must never feel a cause is hopeless — men must never feel an enemy cannot be beaten!
