If Eliezer had made a "things to know to be a rationalist" post instead of breaking it down into The Sequences, I doubt anyone would have had much use for it.
On the other hand, you tend to need an outline which graduates up to this level of vagueness at some point before writing large, in-depth works.
I came up with an idea today: I think it would be useful to have a list of everything that a typical person ought to do. After all, there is quite a lot of stuff that a typical person ought to do; how else is a person supposed to remember it all?
Here's what I've come up with so far:
Health
Money
Altruism
Interpersonal interaction
Recreation
Responsibilities
Productivity
Skills
Anyone have any suggestions for additions or improvements?
