The Personal MBA

is written in such a way as to be easily digestible in small chunks, and should be highly useful to anyone who doesn't already know a lot of econ and find themselves applying it. I would say it's still worth a skim even if you're fairly confident in this area as a sort of checklist. It doesn't matter if you're not trying to run a business, the lessons are widely applicable.

The best part is that what he tells you to do for investing is really easy and involves almost no choice, which meant I got started immediately while reading more about other life changes. He also drills into you that the naive cost/benefit calculation for outsourcing small home repairs done by a lot of us geeks misses less obvious costs of outsourcing and under-counts the benefit of learning skills, which was a big update for me.
