Another huge help for me is having binders to organize my life. I have binders for everything. For my car, my RV, my home, for my personal happiness studies, for bills, for some classes I take, for pursing SSI, for my mental health, my physical health, for Look Books for my home decor ideas, for my pets, my Flylady control Journal, my money journal...
I don't have to try to remember anything this way. I can consult all the paperwork and notes on everything at complete ease. And I like adding to and organizing my binders - it is a very soothing activity. It makes my world make sense.
