Every new year, we promise ourselves new lives, new looks, new selves. Yet by the end of the first week of January, how many of us still feel that motivation, that tug toward self-improvement? Think for a moment now: what if every day were lived with that sort of mindfulness and deliberation, of keeping our promises to others and ourselves? What would that feel like, and who would we become? We might not necessarily become better, or wiser, or more beautiful, but perhaps we would live with a greater appreciation for incremental change, the gradual completion of a project, the assiduous chiseling of an idea, the slow and uncertain progress that underlies day-to-day existence.
