Relationship with yourself

I just had a sentence blow my mind in module 5 of how to feel better. I think my relationship with myself suck! And it has been sucking for a while. And I do this in some other aspects of my life too. How do I improve this relationship with myself? I think that is they key to many of my challenges.

“I have a scheduling issue. No, you have a relationship with yourself issue….. honoring your decisions ahead of time it completely changes your relationship with yourself. You start trusting yourself.”
