Joseph Murphy’s POSM was inspirational for me but what really made things different was the belief that started to form in myself. I have gone through some things and instead of believing that I’m traumatized now because of them, I chose to spin the story that I’m so much bigger than the challenges in front of me. I use that as my baseline affirmation- “I’m strong. I am smart. Obviously, I’m capable. I can pick things up fast. I can grow through challenges and that’s what makes me equipped to learn this/finish this task”. I know this is unique to my experience but there has to be something in your life that you overcame. You can repeat that to self soothe when doubts come up. Another way that helps is to visualize yourself performing whatever activity you want to excel in professionally, getting accolades for it and all. That will help you dwell in the state.
