The Bad-Day Deck

Keep a habit alive on the days it usually dies. One card per bad-day scenario, each with the mechanism behind it and one move you decide in advance, not at 11pm.

The mechanism inside

Implementation intentions (Gollwitzer and Sheeran, 2006) aimed at the specific days habits die: the what-the-hell effect after a slip (Polivy and Herman, 1985), habit decay that flattens instead of resetting (Edgren et al., 2025), and self-compassion outperforming a pep talk after failure (Breines and Chen, 2012).
