Monday hour 1 question

I map out my week and do all the things. I’m pretty good about honoring my schedule but there are days where my primitive brain is like “Nope, no f— way. This is too much. You need a break. The noise is too loud. Step away from the madness for a hot second.” I go into full-blown resistance. This happened yesterday and I was like of course I don’t feel like doing this, but I can do it anyway. It felt like physical resistance just as much as emotional resistance. My main question is, how do you know when to listen. How do you know if you are pushing yourself too huge and actually do need a break? I forced myself to keep pushing through but I’m super curious to know how you can tell if the desire for a break is self-compassion or just the easy out?
