I remember I used to do that in undergrad, and it worked for me at the time. I'm interested but cautious about trying it out again, because I think I might have been using Bad Vibes (shame, guilt) back then as motivators for the self-discipline required to implement it.
I don't want this to be a form of self punishment. As in, *do this thing, or else be miserable*, which I feel like it eventually drifted into.
