Daily commitment is easier than occasional commitment. Michael Phelps’, success as an Olympian was due to his daily commitment to being his best. When you’re fully committed, decisions are clear cut – you’re all in, no second-guessing. It eliminates the mental energy spent on debating whether to stick to the plan or not. With 99% commitment, you leave room for doubt, excuses, or half measures, which can drain willpower in create internal conflict. 99% is a battle. 100% is a breeze.
