I've got a dozen hobbies that I don't have enough time for now. Plenty to do, watch and read. I'd probably also have a go at building a greenhouse to grow more of my own food.
I'm right there with you. The world is so incredible!! I could work 70 hours a week on my own hobbies. I've never even though of building a green house; but I bet it would be a ton of fun. There is so much to see and do, how do people become bored and listless.
