Walk(a)way?

If I use this image as some kind of visual metaphor, then somehow in the next few months I have got to walk all the way to the other side. Looks easy, but then I've got to do it without convincing myself I can't, jumping off and going the long way or just turning around and giving up. I'm not really a quitter when I start something but I am very scared of failure. Just the thought of failing freezes me into angry and resentful inaction. I know what I have to do and I know I can do it and I know the biggest obstacle in my way is myself.
