can't vs won't

do you remember when you were a child and asked "can i go to the bathroom" and the answer was not yes or no but rather a correction? because the proper way to ask is "may i go to the bathroom".
these distinctions are important.
bearing this in mind, consider how we are likely to speak when we are on a diet. one might say "oh i can't eat one of those frosted doughnuts. i'm on a diet!". but this is stinkin' thinkin'! because fact is, we can eat the doughnut (or whatever) if we want to...our mouths can chew, right?
when we say can't we are denying ourselves a pleasure we may think we deserve. and eventually we will build-up resentments which will culminate in a splurge or eat-fest or worse the end of our eating program.
the place we want to be in body/mind/spirit is to say "i won't eat that doughnut and further more, i don't want that doughnut. because my own good health is very important to me." or even "i respect myself too much to eat that doughnut". no denial there! just self empowerment, awareness, personal responsibility.
try it!
