This is something I've been thinking about a lot lately, myself. I totally struggle with akrasia and executive functioning, and I find I have more willpower if I do things socially. I've been using friends to go to the gym for the past few weeks. I've actually been rethinking my relationship with leadership because of it: I used to hate being the leader (preferring to just be left alone), but now I'm thinking that I need to lead in order to do the things I want to do.
