Actually no, I'm analytical by nature. That's another reason I play Go: it forces my brain to balance its thought processes out. I do get paid to overanalyze things though.

Besides, budgeting is a good skill; and lack of projective analysis is what makes poor people poor. They continue to get scammed by businesses based around selling you things for "low, low prices!" which require a much bigger total investment (like clothes that fall apart, shoes that fall apart, washing machines that fall apart, cars that fall apart...). The only reason I could afford all my nice bike gear so far (along with some other luxuries) is because I eliminate a lot of costs by better planning. This is counterbalanced by my tendency to consider education expensive, and thus dive head-first into things and somewhat overspend on new stuff (for example, I'm probably going to rid myself of the bike basket and get panniers; I may go with double-sided clipless pedals some day; etc).

New towel every other shower, yes; although I'd use one every shower if it was convenient, cheap, and efficient to wash them. It'd be somewhat nicer. I also don't use shampoo at all btw; my barber loves this, because she has a degree in cosmetology and wanted to be a hair stylist, and well... my hair's gotten soft like puppy fur and naturally has good hold. Well, it did after the first 2 months (a LOT of excess grease until the sebacious glands calmed down! Degreaser is NOT good for your head!). So she has a field day with this

I'd just prefer to not rewear. I have, but I prefer fresh, clean clothes when I go out. I just don't want to put up $500 for a full week's supply (now that I've gone from "2 days a week to work" to "every day, everywhere" commuting), and wouldn't mind putting up 10-15 minutes a day to sidestep that.

In any case the consensus here seems to be between "Reuse everything" and "I hand wash stuff" ... interesting. I don't even know how to hand wash clothes, though I guess the process is obvious: soap, water, grease (elbow recommended).
