Nonviolent Communication by Marshall Rosenberg is a great book teaching a compassionate way to talk to people even if you (or they) are angry.
Joe VitaleYou want to become aware of your thoughts, you want to choose your thoughts carefully and you want to have fun with this, because you are the masterpiece of your own life. You are the Michelangelo of your own life. The David that you are sculpting is you. And you do it with your thoughts.
Joe VitaleWe deny ourselves the smallest comfort or pleasure; even if it only costs a few dollars. This is not prosperous spending. Prosperity says you can have red bell peppers instead of green, rib eyes instead of sirloin, and romaine instead of iceberg. It's not about spending everything you make, but enjoying what you do spend without felling guilty about it ... The positive feelings and emotions that prosperous spending brings is what attracts more positive things in your life.
