Take 15 minutes daily, thinking of pleasant scenarios regarding your body, with the sole intent of enjoying your body and appreciating its strength and stamina and flexibility and beauty. When you visualize for the joy of visualizing rather than with the intention of correcting some deficiency, your thoughts are more pure and, therefore, more powerful. When you visualize to overcome something that is wrong, your thoughts are diluted with the "lackful" side of the equation. In time, your physical condition will acquiesce to your dominant thoughts.
We would like you to reach the place where you're not willing to listen to people criticize one another... where you take no satisfaction from somebody being wrong... where it matters to you so much that you feel good, that you are only willing to think positive things about people... you are only willing to look for positive aspects; you are only willing to look for solutions, and you are not willing to beat the drum of all of the problems of the world.
It's not necessary for you to exacerbate your contrast with struggle in order to get it into a higher place. It is not necessary to suffer in order to give birth to desire. But when you have suffered and you have given birth to desire, so what? You've got a desire. Turn your attention to the desire. Think about where you're going and never mind where you've been. Don't spend any more time justifying any of that stuff -- Abraham
