A great list and a very valuable post.

One of the things I have noticed that holds people back is a common error of thought - catastrophising - it is common in dieting for example - you make one mistake and eat something you shouldn't and you pack the whole thing in. You tell yourself "It's ruined" or "I may as well give up" - well if you just accept the mistake or setback and then move on without giving up you start to realise that this kind of thinking is pointless.

Setbacks, hurdles, roadblocks call them whatever, are a normal part of life. As long as you accept them and keep going you can achieve anything.

Anyway. All the best I look forward to reading more of your posts and have added you to my follow list.
