Not sure about specific details, but I have a feeling that it is easy to make a mistake of thinking about "what is easy to buy & would be convenient". Sure, it is great to pay someone else to do your dishes, but is that really the best way to convert money into awesomeness?
Instead I would recommend making a specific plan about becoming more awesome, and only then to search for a specific point of the plan where extra money can give me the greatest bonus. For example, let's say I want to become a rock star. I can pay someone to do my dishes, which will give me more free time, which I can spend playing the guitar; and that is useful. But maybe it would be more useful to spend the money on the guitar lessons, on musical instruments, on someone to research what is the best way to play the music or where is the best opportunity on the market, or even on someone to regularly remind me to play the guitar.
In other words, if you have decided on a best way to use your money to improve your life before having a specific plan of what you are going to do, it is probably not the best way.
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.
