You want to distinguish between essence and accident because [[You are finite borrowed time]], and you don't want to waste yourself. Indeed, you want to make the most of yourself. What does that even mean? I can tell you what it doesn't. Making the most of yourself doesn't mean being efficient and productive because of the [[Efficiency trap]]. Also, remember that [[Efficacy, effectiveness, and efficiency aren't the same thing]]. Being efficient means achieving the intended outcome most economically, but what if that outcome is unimportant? [[Be effective first, then efficient]].
