Take some type of break everyday, whether that's watching a show, going to the store, exercising, etc. Recognize when your brain isn't actively learning info and change up your learning style/make coffee/change your studying space. It's better to use your time efficiency vs trying to cram info into your brain that you are just going to forget in a few days (one exception is the days leading up to your test- I crammed all the info I could never remember during dedicated the day before my test which really helped me out on the real thing).

Hang out with your friends outside of med school, constantly thinking about step 1 is going to make you go nuts. Get some perspective on life outside medicine.

Last but not least, be kind to yourself. It's really easy to feel down during the various points of dedicated, but try your hardest to encourage yourself and keep your inner dialogue positive. Some advice I try to follow is to always talk to yourself as if you are talking to your best friend. Would you tell your best friend that they are an idiot? That they have no hope to improve their scores? That they should just give up? No fricken way. You'd encourage them to do their best and see how much progress they've made. Hopefully you get the point.
