Well, changing the story you tell yourself involves self-reflection. Figure out what's holding you back in the current story, set clear goals for the new one, and make a plan to gradually shift your mindset and actions accordingly.
To change the story you tell yourself, start by being aware of your thoughts and the narrative you've been repeating. Analyze what's not serving you and come up with a more positive and empowering version. It might take time and practice, but consistency is key.
First, you need to recognize the patterns in your current story. Then, think about what you want to change and why. Finally, start consciously replacing the old elements with the new ones.
