... Incredibly difficult to change your self-talk. It will take work but my goodness is it ever worth it!! Stick with it for a year, just try to give yourself grace and have compassion. A dip comes... gently say 'Oh course you would go back to old patterns, that doesn't mean you are that old person still, you are growing and are brave for continuing to fight.'
You can't go after what you want if you don't know what it is that you want. That's why "vision" is so important. Make it clear what you're trying to achieve so you can more effectively channel your time, energy, and resources into achieving it!
