Whenever you stop yourself from doing something that you want to do because of fear, personalize it. Turn that voice into a person – imagine someone standing in front of you, demanding that you stop your attempt. Telling you that you’re not allowed. That he forbids it, in fact!
I’m not sure about you, but external people telling me I can’t do things tend to make me want to do those things a lot. So much that it’s probably a fault on its own, but hey – maybe I can turn it to some good here.
Because if I wouldn’t let Mr. Fear tell me that, why should I listen to the same words in my own head?
