I read and wrote down, "The strength of a muscle may depend on the confidence with which it is used." I shared this with one of my health practitioners and he'd like to know the source. Normally, I have a very good memory, but I'm drawing a blank finding this. I'm sure it was here and any help would be appreciated. Thank you, Judy edit: I found it. It was from Claire Weekes in a checklist Herbie posted. Thank you, search box!
