Like so many people above, I have a hard time recognizing my limits and listening to my body. One thing I'm really working on is dealing with falls and other minor accidents. It's really tempting to pick myself up and carry on with what I was doing, to not lose momentum, to not do anything so embarrassing as ask for help (or even accept it when it's offered) because it would be so much simpler if I wasn't hurt so let's just act like I'm not. I don't go so far as to follow concussion protocols for every head bonk, but I try to at least stop and acknowledge that there's a problem.
