Random thought 2:
The next time you get a car, get one with a thermostat. It's an uncommon option and I don't know how much it costs, but the Ford Taurus my parents bought off the lot happened to have one. In other cars, the heat and air conditioning tend to overshoot, leaving me cold in the summer and hot in the winter on long trips.
Turn down the heat/AC once the car has reached temperature? It's been -10C or so here for most of the last month, and I turn the heat down halfway on any long road trips, because blasting it for more than 20 minutes is silly. It's really easy to get a thermal equilibrium with a traditional car thermostat.
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.
