Nobody outgrows popping bubble wrap. Keep a few small joys you never have to explain.

Some pleasures have no purpose, no improvement attached and no story you could tell about them, which is precisely their value. As you get older there is quiet pressure to justify your time, and the first things to go are the ones that cannot be defended. They were doing more for you than the defensible ones.

Keep at least three things you enjoy for no reason and protect them from being made useful. Do one of them this week without turning it into a project. If someone asks why, it is entirely fine to say that you just like it.
