To doubt is natural. It’s how we are wired, but you don’t have to buy into it. Remove your identity from the equation. In the end it does not matter who people think you are. It’s in their heads and their heads alone. Remember, their experiences are what will form their opinion of you. And you have little control over that. All you do have is your own dedicated agency. So use it. Take your time and settle in. Too often we are trying to cover something up and not letting it breathe.
