I want my day-to-day life to boil down to activities increasing four elements: strength, willpower, enjoyment of life, and happiness. These four concepts are of two dimensions: mental-physical and induction-acceptance. So
physical + induction = strength
mental + induction = willpower
physical + acceptance = enjoyment of life
mental + acceptance = happiness
Question any activity that does not contribute or contribute too little to one of the above qualities. Squeeze your life out of the time! As for practical matters, I start with doing at least one exercise a day for each category. Strength: physical exercises up to suffering. Willpower: doing a non-urgent unpleasant task or having resisted a strong temptation. Enjoyment of life: have a pleasant treat. Happiness: damn!
