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.
Alternative: commute effectively. Taking a train to NYC from Long Island I get almost 2 hours to read/watch lectures or entertainment. Some days these are 2 best hours of the day.
A few months ago I got a new job that required me to commute for two hours each day. I tried doing many different productive things while sitting on the bus (the means of transportation I used), including reading, listening to audiobooks, watching videos, and even meditating. Eventually, however, I reached the conclusion that doing Anki reviews (using the AnkiDroid app) was, by a wide margin, superior to all these other activities. If you own a smartphone, you might want to give it a try. (And if you don't own a smartphone, you might want to consider obtaining one.)
