Change becomes much more achievable if you pay attention to who you are and insert routines that take advantage of your strengths, tendencies, and aptitudes. With self-awareness, you can cultivate the habits that work for you. Consider, for instance, differences in circadian rhythms. Circadian rhythms reflect our natural tendencies for sleeping and waking and influence our energy and productivity at different times in the day (11). The odds of success to improve your fitness won’t increase if, for example, you decide to rise an hour earlier to exercise each day when you happen to be a “night owl” rather than “morning lark.” Self-awareness includes knowledge about other aspects of self as well, such as whether you are a marathoner, sprinter, or procrastinator; under- or over-buyer; simplicity or abundance lover; finisher or opener; and familiarity or novelty lover (8). It also includes whether you are promotion- or prevention-focused, and whether you like taking small or big steps (8). and new habits, on average, take 66 days to form (12), so the more strategies used, the better.
