I too have a to-do list that I will never drain. The 24 hours in a day are an immutable tyrant governing all of our choices. Ask anyone who has taken a sabbatical for a month or two...most people spend the year leading up to sabbatical dreaming of all the hobbies, back-burnered side projects, house repairs, travel, etc. they will tackle during their sabbatical. Then reality hits and you only get 1/4 of them done before having to go back to the grind.
