I am a minimalist (Essentialist) by choice, but a maximalist regarding knowledge and experience. Try and do everything you can, that way you know what does and doesn't work. Done. Anything else is overly reductive. You can't know how to do anything if you do or experience close to nothing.
Leisure is good, I am a ferverent advocate of Veblen philosophy, but if you want to be wise use your leisure to do the maximum you can and want to do with that time. Leisure is different for everyone, reading, gaming, sitting on the beach, making art, but if you want to be /wise/ with your leisure you have to do everything you want to do! Focus a lot, or focus a little, you just have to do everything possible to fuck up as much as possible.
