I'm still really happy with buying a massage cushion (not this one but about this type and price). I bought it shortly after I got my first job, and wanted one, noticed it wasn't too expensive (per massage), and went for it.
It's a nice treat that still feels luxurious and indulgent, so I also desire other indulgent things less.
Plus, I named mine "Adulthood" since I could buy it because I was an adult and my money was mine to do with as I wished. Thus my roommates and I were prone to say things like:
"I never dreamed Adulthood would be so wonderful"
"Sometimes Adulthood is all that keeps me going"
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.
