I agree. Perhaps this should be qualified as "most important habits that are only recommended in the Rationality community". Otherwise there are plenty of other skills we can add (another example - start saving money early, etc).
Seems like the second list would be way more useful. I'd rather create that, and perhaps have a simple tag like #rationality so you could filter down to only those habits.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
