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.
Cognitive load. Shopping for the best price online can be just as stressful and just as much a waste of time as shopping in real life. By contrast training yourself just to buy the first item that looks good enough will (TDT) save you lots and lots of money/time/stress in the long run. 2 Day shipping as opposed to variable shipping (and tracking your packages) means you can buy a lot more items without having to plan too far ahead. I can often go a day without something but can't go the possible 5-10 business days that many other places offer.
Amazon student is a good tip. anyone with access to a .edu email address can get it free for a time and half off after that.
