I had taken “young” in Trevor_Blake's comment to mean “in your twenties”.
Then I agree. I just didn't see that word used in your response, so I misunderstood it to be without time limits.
(By the way, most people seem to use the word "young" meaning "age <= my_age" or later "age < my_age". Just ask a teenager whether twenties is young or old. Then ask a 50 years old person whether thirties were young or old. So an advice based on "while you are young" has very high potential to be misunderstood.)
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.
