I'm a fan of Dr. Morita's approach to such problems. "Trying to control the emotional self willfully by manipulative attempts is like trying to choose a number on a thrown die or to push back the water of the Kamo River upstream. Certainly, they end up aggravating their agony and feeling unbearable pain because of their failure in manipulating the emotions.
—Shoma Morita, M.D.
...... At first glance, it sounds a bit like "just do it," but there's more to Morita Therapy. Anyway, that's my thought. I'm always scared and nervous before training, but now I'm just more used to scared and nervous. Works for me and I don't ever miss training. ..... http://en.wikipedia.org/wiki/Morita_therapy
