I agree with the message but this post is really lacking. Only 2 sentences are spent on why founders need hobbies and much more on a list that, as one of the other commenters already pointed out, is irresponsibly expensive for most founders. It would be better to hear how a founder with a hobby is more successful thanks to his hobby.
Not only is it irresponsibly expensive, those don't really sound like hobbies (not in the context they are putting it anyways). A hobby is something you dedicate and involve yourself with that isn't your profesional line of work - which means spending a significant amount of time with it. Doing something once or twice is not a hobby.
The items on that list sound more like Bucket List items - something you'd do once and never again. That makes an experience, not a hobby.
I do agree with the premise though - it's important to have hobbies. Personally I do a lot of photography - film specifically so I can spend less time in front of the computer.
