This might go against the grain: I advise people to think more about themselves than others.
Too often I see people working themselves to death with obvious symptoms of fatigue and stress helping their kith and kin beyond any reasonable measure. The more immediate case is the person trying to save something or someone from a fire and dying in the process. They would be better advised to think of themselves, raising their wellbeing and making others more self reliant in the process. Or more effective overall.
What are we doing to make this world a better (epistemically or instrumentally) place?
Some answers to this question are already written in Bragging Threads and other places, but I think they deserve a special emphasis. I think that many smart people are focused on improving themselves, which is a good thing in a long run, but sometimes the world needs some help right now. (Also, there is the failure mode of learning a lot about something, and then actually not applying that knowledge in real life.) Becoming stronger so you can create more good in the future is about the good you will create in the future; but what good are you creating right now?
Rules:
Top-level comments are the things you are doing right now (not merely planning to do once) to improve the world... or a part of the world... or your neighborhood... or simply any small part of the world other than only yourself.
Meta debates go under the "META" comment.
