@pliepla I get where you are coming from. It seems as if you are frustrated that the demons are coming at times you don't want them, i.e. When you slow down. Did I get that right?
For me, I have a hard time getting started! I find myself getting stuck in the I don't want to do that realm. I wish I had your drive to stay busy!

Besides that a thought came to mind. I don't know if you have tried to do this consistently, but I have heard it helps. Meditations it slows the brain down and helps calm the body. My thoughts are it may help you become who you want to be. What do you think?
