This is an extension of a comment I made that I can't find and also a request for examples. It seems plausible that, when giving advice, many people optimize for deepness or punchiness of the advice rather than for actual practical value. There may be good reasons to do this - e.g. advice that sounds deep or punchy might be more likely to be listened to - but as a corollary, there could be valuable advice that people generally don't give because it doesn't sound deep or punchy. Let's call this boring advice.
An example that's been discussed on LW several times is "make checklists." Checklists are great. We should totally make checklists. But "make checklists" is not a deep or punchy thing to say. Other examples include "google things" and "exercise."
I would like people to use this thread to post other examples of boring advice. If you can, provide evidence and/or a plausible argument that your boring advice actually is useful, but I would prefer that you err on the side of boring but not necessarily useful in the name of more thoroughly searching a plausibly under-searched part of advicespace.
Upvotes on advice posted in this thread should be based on your estimate of the usefulness of the advice; in particular, please do not vote up advice just because it sounds deep or punchy.
Avoid weird people.
(Negation of #1 geek social fallacy.)
Of course this advice works only with some definitions of "weird", and I don't want to make it too long, but I feel it is very useful. The point is not to avoid anyone who is off-center in any Gauss curve, but to avoid specifically people who impose a huge cost on you and on people who associate with you, usually because of their serious lack of some social skill. Certainly, nobody is perfect, but don't commit the fallacy of grey.
Everyone head for the exits.
This site is full of weirdos by prevailing societal conventions.
I'd say instead to advertise what kind of person you are, so that you attract and repel the right kind of people.
