Gaining satisfaction through accomplishments is and will always be a slippery slope, because there will come a time when you realize you have accomplished all that is within your power to accomplish in the realm of good, and will have nowhere else to turn but to the realms of greed and powerlust to find the satisfaction you crave.

Always think at least two steps ahead [in everything, with everyone].

What is a secret? It is much more than knowledge shared with only a few, or perhaps only one another. It is power. It is a bond. It is a sign of deep trust, or the darkest threat possible.... Be very chary of revealing your hoarded secrets. Many lose all power once they have been divulged. Be even more careful of sharing your secrets lest you find yourself a puppet dancing on someone else's strings.

You gotta be careful: don't say a word to nobody about nothing anytime ever.

You can get addicted to trouble if you're not careful.

Hatred gives you nothing, takes nothing from you, but destroys everything you have! Be careful of ideas of hatred that comes into your head. Destroy them before they make nests in your mind!

Speaking a painful truth should be done only in love - like wielding a sword with no hilt - it should pain oneself in direct proportion to the amount of force exerted.

Be careful how you live your life.

Be careful whose advice you heed to!
