Letting Go

I am paralysed by decisions and tend towards not acting when I should. I am not sure why I put this sort of pressure on myself but I am terrified of making a mistake. My definition of mistake generally being more focused on whether or not my decision is good for others rather than whether or not its good for me. What if someone else dislikes what I decide? I know that sounds silly but its a real concern for me. I constantly seek the approval of others - way too much to be a healthy thing.
