I'll say this. You have things that you want to do. You are probably not able to do all of thing things that you want or will want to do. You will not suddenly be better at doing these things that you want to do if you burn yourself out. I thought the idea of self-care was for ninnies for a big part of my life. It doesn't have to be dramatic, or take a lot of time, but you need to be your own first priority. In my case, I have an urge to speed-walk everywhere in the hospital where I work. I know that I get tired out easily, and that I am less effective at my job if I am tired. So in this instance, self-care is knowing that I need to be mindful of my walking speed, and while I don't dawdle going from place to place, I also don't push myself to be super early to everything.
