Good for you! Most of my clients who struggle with this issue are were either raised in ways that discouraged them from expressing their thoughts and desires (abuse, religion, etc), or women, who are generally socialized to put others needs above their own. This is here for folks who need it.

I mean, I'm not usually a fan of using shame as a motivator for change, but sometimes you just have to go there. Everyone knows you use butter, liberally, and on both sides of the bread.
