“The trick is not to get hooked on the highs and lows and mistake an activated attachment system for passion or love. Don't let emotional unavailability turn you on.”

“Romantic love is a passionate spiritual-emotional-sexual attachment between a man and a woman that reflects a high regard for the value of each other's person.”

“If you always attach positive emotions to the things you want, and never attach negative emotions to the things you don't, then that which you desire most will invariably come your way.”

“Just be careful. Passion is a bridge that connects love and hate. When you're standing in the middle of that bridge, don't let yourself get turned around. You've got to make sure you know which direction you're heading. Watch yourself.”

“Don't mistake activity with achievement.”

“I believe that the best way to create good living conditions for any animal, whether it's a captive animal living in a zoo, a farm animal or a pet, is to base animal welfare programs on the core emotion systems in the brain. My theory is that the environment animals live in should activate their positive emotions as much as possible, and not activate their negative emotions any more than necessary. If we get the animal's emotions rights, we will have fewer problem behaviors... All animals and people have the same core emotion systems in the brain.”
