I don't know if it's so much fear of success, or that it frees so much energy we can't contain it. It stimulates so much anxiety that we can't contain the anxiety. What happens is, we get a glimpse of what it's going to be like to be this fresher, freer self. But we'll often just not go back to follow up. And then, by that time, I'll have gotten a cold and just won't show up.
Awareness is such a powerful tool that just becoming aware changes everything.
