A lack of faith or confidence in oneself.
lack of confidence in one's own motives, ability, etc.
This is what I have to learn to stop doing. I am always doubting my abilities and second guessing myself. I need to learn to just let it go and that what I do is good enough and that I am good enough. The one thing I find myself doing is I will say that I going to do something one way and then second guess myself and think should I do it another way and then don't end up getting anything done and I'm back to where I started. It would be nice to just turn my brain off sometimes and just not have to think about anything at all and just let it all flow out.
I'm going to try and work on not self doubting myself and to be happy with what I do.
