Why does “productivity” need to be the end? I like some degree of randomness because it makes my life more interesting and enjoyable. In a way, that can make me more productive if I feel more inspired or motivated by it. But I do it because I like it: taking a random road on my daily commute, talking to a random person and seeing what happens, trying a random new restaurant, etc. I have a highly random life with very little routine or predictability.
