Thing I'm chewing on this week to get through burnout and demand avoidance (which are inextricably linked):
asking myself what is one thing I can do today to make future-me grateful. It frames tasks as a form of self care and coming from a place of compassion and love.
It has been working so far. I don't celebrate it, as putting too much of my own inner focus on my own success is a form of pressure and does not feel good.
I try only to think about it as "I love you, future self. Here is a gift you can enjoy the results of later when you're feeling tired cuz that's pretty much a constant"
