The Psychologist//Therapist For The Navy Seals:
"I don't want to teach you how to be a glass-is-half-full guy. And I definitely don't want you to be a glass-is-half-empty guy. I want you at the end of the day to say, that glass of water has 6 ounces of H2O in it right now."
Such a great quote. I was reading an article and he was basically just saying how when special forces guys are getting down on themselves, they'll be thinking in very broad generalities, so he forces them to get specific and when he does that, a lot of the shit dissapears.
