Really cool post, I have a fear of hurting myself and then injuring myself so that I own't be able to provide for my family (both temporary and permanently), this is something I really have to learn to overcome when I go cross-country skiing, otherwise I do this with a break on.
That's the weirdest thing, is not it?
You can not avoid injuring yourself, it is not in your control
Which makes it even worse as you keep having that fear in your head that stops you from giving 100%
