“…refrain from comparing yourself to others, especially rock stars in your field…Comparison is the path to perpetual misery. There’s always someone richer, faster, hotter, or whatever.” — DeMarco, “Unscripted”

Focus on yourself. Focus on 改善 (kaizen). Don’t look outside yourself for competition or comparison. You already have the best (psychologically healthiest, most perfectly calibrated, most fun, most interesting and most fulfilling) opponent of all; you already have a competitor: you yesterday.
