If you have trouble getting into an exercise routine, try this. Join a gym, and go every single day and do the same exact thing every time. For a lot of people, doing something every day is a lot easier than coming up with a schedule that changes depending on the day, especially if one of the changes is 'do nothing on Sunday' (recipe for doing nothing on Monday too, and then forgetting about the whole thing).
What I do is this. I wake up to my alarm, and then I immediately go eat a light breakfast, and then head to the gym. Once at the gym I stretch for like 5 mins, run on the treadmill for 5-10 mins, do a couple sets of military press or something, and then go to the sauna. Hits all the major pieces. Flexibility, cardio, lymph movement, resistance training, sweating, etc. Once I finish at the sauna, I take a shower, put on fresh clothes, and then start my day. I essentially use the gym as my 'morning routine'. I'm not ready for anything until I put on fresh clothes after my (quick) workout.
Even if you exercise at home, do the same exact thing every time. (Deciding what exercise you want to make, and how much you want to make, already consumes willpower.)
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.
