Thinking of my life as a tradeoff between time, energy, and money [1] was a key factor towards my decision to take a 1-year sabbatical as of June. Similar to that trope about working with contractors: "time, quality, cost: pick 2" (i.e. we can do the work fast and high-quality but it will cost you a lot; we can do it high-quality and cheap but it will take a long time; we can do it cheap and fast but the quality will be low).
