If you want to make information stick, it's best to learn it, go away from it for a while, come back to it later, leave it behind again, and once again return to it - to engage with it deeply across time. Our memories naturally degrade, but each time you return to a memory, you reactivate its neural network and help to lock it in.
I have a ridiculously beautiful wife who's super sexy, and as long as she's happy with me, I don't need to look in the mirror and think, "How do I stack up next to Bradley Cooper? Would Cooper rock this shirt?" Doesn't matter. He does not have your wife. You do.
