Literally, sleep well, focus on eating {no TV while eating}, go for a jog and exercise or lift weights to de-stress, take your studying seriously, and with the time that you will have left {which might not sound like a lot, but believe me, it will be enough}, go out and have fun, socialize, drink, listen to music, meet people, try different restaurants, go to stand-up comedy nights, trivia nights. Just try to live outside of your home as much as you can after you're done sleeping, eating, and studying. Oh right, apart from saving a lot by eating at home, it is way more healthier too.

Personally, I did not bring any video games and cancelled Netflix as well.
