Relatedly, it took me a while to appreciate that seeking out and organizing the best knowledge on a topic is, for me, just a form a procrastination. Its ok if I'm doing it for fun. But if I want to learn, the key seems to be that every single day I start the day learning or reinforcing something, and do no other activity until that one is completed. A somewhat related thing I learned in medical school, is that many people have an internal cue for when you've really learned something. When you have re-visited something for the nth time, and the feeling you have is a deep level of annoyance that you are rehashing the same thing again, that is usually the signal that it will stick. May not work for all but worked well for me and the folks I shared it with.
