Teach your friends!
For me, I can study quietly at my dining room table for 6 hours, and still not get the same result as simply talking to my freinds about what I learned in class today for 10 mins. When you're teaching others, youre also teaching yourself. And lets be honest, nursing is really really cool, I guarentee your friends wouldnt mind listening to you talk about IV placement or "how super rad the lungs are". Share what you're excited about with whoever will listen! It helps I swear
