Within the study of habits, certain tensions reappear: whether to accept myself or expect more from myself; whether to embrace the present or consider the future; whether to think about myself or forget myself. Because habit formation often requires us to relinquish something we want, a constant challenge is: How can I deprive myself of something without feeling deprived? When it comes to habits, feeling deprived is a pernicious state. When we feel deprived, we feel entitled to compensate ourselves—often, in ways that undermine our good habits.
