Well, okay, so you're a highly unusual individual and on the basis of this, you're arguing about the advisability of various things for other people... Your advice kind of boils down to "become like me", doesn't it? Which, of course, is a whole other issue.
No. My advice is to look at the various possible usages of your time and rationally access which benefits they provide. To the extend that challenge is "please become more like me" I find it surprising that someone raising that objection against myself at lesswrong. Maybe I take some ideas about rationality too seriously?
I don't do martial arts classes (for complicated reasons that don't generalize well to the general population). I don't to improv comedy classes yet you will find that I recommend both of those activities because I consider them high value.
If you aren't a person who's good at telling jokes your first improv comedy classes might not be very funny for you. They might be highly challenging. If you take that to conclude that improv comedy classes are the wrong thing for you, then I think you are missing an experience that will bring you forward.
Well, your whole argument seemed to me to be: certain hobbies have various benefits, so you should change yourself to be able to engage in them to reap those benefits. That struck me as a bit far-reaching, hence the "whole other issue" remark.
On ChrisHallquist's post extolling the virtues of money, the top comment is Eliezer pointing out the lack of concrete examples. Can anyone think of any? This is not just hypothetical: if I think your suggestion is good, I will try it (and report back on how it went)
I care about health, improving personal skills (particularly: programming, writing, people skills), gaining respect (particularly at work), and entertainment (these days: primarily books and computer games). If you think I should care about something else, feel free to suggest it.
I am early-twenties programmer living in San Francisco. In the interest of getting advice useful to more than one person, I'll omit further personal details.
Budget: $50/day
If your idea requires significant ongoing time commitment, that is a major negative.
