Recreated

I understand that over a 7 year period, every cell in your body is replaced. I am wondering what kind of a new life I could create for myself if I really tried to build a better me over the next seven years. Primarily, what paths in my brain could I reprogram if I thought only positive thoughts from now on?

This came back to me yesterday as I was collapsing under the stress of a new job. I don't want to do that. And I would love to look back in 7 years and realize I've become a new person with new ways of coping with the challenges of life. I'm going to try. I'm going to work on replacing dysfunctional and negative thoughts with accurate, positive, encouraging ones. Thoughts that allow me to do what I need to do, and to live life with joy. It will take tremendous effort - but I think it will be worth it.
