Any time you sincerely want to make a change, the first thing you must do is to raise your standards. When people ask me what really changed my life eight years ago, I tell them that absolutely the most important thin was changing what I demanded of myself. I wrote down all the things I would no longer accept in my life, all the things I would no longer tolerate, and all the things that I aspired to becoming.
Tony RobbinsThe birth of excellence begins with our awareness that our beliefs are a choice. We usually don't think of it that way, but belief can be a conscious choice. You can choose beliefs that limit you, or you can choose beliefs that support you. The trick is to choose the beliefs that are conducive to success and the results you want and to discard the ones that hold you back.
