Stretching the Mind

On Saturday I went to a yoga class at my gym and the teacher said something that changed my life. First he was going on and on about doing you own practice and not to compare yourself to anyone else. The same stuff yoga teachers always say and the same stuff we need to hear over and over. But then he said, "When things aren't going right for us we have a default feeling." When he said that I realized what mine was. And now that I know what it is I can change it. What is yours?
