So far I'm learning this year that if you don't feel good, you're not going to do good. Take care of you. Shower because you haven't showered in three days, wash the pajamas you've been wearing all weekend, organize your living space.
Take care of the basics first. Then focus on doing what makes you happy. For me, that was making a big cup of tea and crawling into bed to read East of Eden last night. Then when my mind couldn't focus anymore, I put earphones in and listened to music while I worked on a new knitting project.
I slept better last night than I have in ages, and that says a lot to me about the ways that I treat myself on the daily grind of life. Self care is so important, and feels so good when you actually allow yourself to do it.
