What you tell yourself about yourself is a story, not a fact. It may feel like a fact because you’ve been attached to that story your whole life. You’ve kept that story alive with your thoughts and behaviors.
If the story you’ve been telling yourself about who you are doesn’t feel empowering, you can change it.
Don’t believe a story that is making you feel powerless. Your story can be re-written and at any point if you’re willing. You can decide on what you want the plot to look like and decide your role in the story.
