Wow, you have a lot of resolutions and things going on for 2021. Good luck with all of them. I feel the most important of all is to be resolute to the fact that you will work on not letting others dictate your time and energy. Back away and say "no" I don't want to, I don't have the time, I don't believe it's right, or I can't devote my full attention to it right now. I had to learn this the hard way when I backed away from family reunion planning. Others will put more on you and not think anything about it IF you let them.
I feel this will be the most important change in 2021 and alleviate outside stressors in your life.
Take care, and go for it. Hope it all works out.
