My favorite tool for building courage is to fully analyze the situation to see if I am logically making the right choice. Also, I think it’s important to look at my motives for what I want to do. I try to calculate the best way I can if I am making the right choice in the best way. At that point even if it doesn’t go well, at least I know that I tried my best to make the decision.
After reading some of the other responses, I am now considering that I might procrastinate between the time when there is something I have to do and analyzing the situation. So I will consider if it might be more successful to end procrastination by analyzing less.
