Don't do what you want. Do what you don't want. Do what you're trained not to want. Do the things that scare you the most.

If you refrain from judging your worst enemy, his children will come to your side. What more severe judgment could come upon an enemy than this?

Don't do unto others what you don't want done unto you.

Sometimes to get what you want the most, you have to do what you want the least.

Another way that you love your enemy is this: When the opportunity presents itself for you to defeat your enemy, that is the time which you must not do it. There will come a time, in many instances, when the person who hates you most, the person who has misused you most, the person who has gossiped about you most, the person who has spread false rumors about you most, there will come a time when you will have an opportunity to defeat that person. It might be in terms of a recommendation for a job; it might be in terms of helping that person to make some move in life. That's the time you must not do it.

My first rule of war, Cat-never give the enemy his wish

Do not do to others what you do not want them to do to you.

...a fate I wouldn't wish on my worst enemy...

If you are your own worst enemy, don't do yourself any favors.

Never tell your enemy he is doing the wrong thing.

Therefore the clever combatant imposes his will on the enemy, but does not allow the enemy's will to be imposed on him.

What you do not want done to yourself, do not do to others.

If you don't want to do something,don't impose on others

In any ethical situation, the thing you want least to do is probably the right action.
