I think I saw that on LessWrong quite recently. That study is trying to refute the claim that income satisficing happens at ~$20k (and is mostly focused on countries rather than individuals). $20k << $75k.
When we analyze these data more formally in regressions we find no evidence of a significant break in either the happiness-income relationship, nor in the life satisfaction-income relationship, even at annual incomes up to half a million dollars.
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.

If your idea requires significant ongoing time commitment, that is a major negative.
