when trying to learn something, engage with it repeatedly on exponential decay. IE. Index cards. Go through them as many times as it take to learn whatever you are learning. Then perform a 20-30 minute context switch. do again. Now wait 1 hour. Do the cards again. Wait 2 hours. Again. Do this until you review those cards at the week level. You can learn almost anything with very high recall 6-9 months later with this method.<p>edit: Sleep is an extremely important component of this. You must be well rested, and preferably do not ingest significant amounts of alcohol before sleeping as that will mess up short term to long term memory mapping from hippo to pfc.
