One thing that you may observe is on how easy it is for your mind to build negative thought upon negative thought. The chatter not only does not stop but it spins a drama that traps and limits you.
From now on, regularly do this exercise instead. Spin an uplifting story that runs like a movie script. Some visualization will be helpful. You build on a story with a positive outline. The longer you can tell this story to yourself the better. It is also best if you can make this story one about having all your goals achieved. When you do this, you start to internalize your goals and dreams, as if they are something that you have already achieved.
