What I do is in the evening before bed write down all things I would like to do the next day. Then in the morning I choose the top three and put them in priority order. I do my best to finish those three, but life is all about change. If something else becomes more important or excites me more, I may chose that over one of the three things I picked. I allso have the list from the night before and can pull things fromit in little bits of time between bigger things.
Today it was my intention to tidy the bedroom and unload, reload and run the dishwasher. However, tidying the bedroom took longer than expected and I really wanted it done. So I used all my energy for the day on that. I added in a few tasks afterwards from my list that were more sedentary (emails and such). But I have a lovely clean bedroom now and it makes me happy.
I don’t think of to do lists as rigid things any more… because I did that for years and all I got was upset that I couldn’t finish them. This works for me. There is always more I’d like to do than I can do. Good luck.
