Do fun things with your friends, travel, live life as it all has to be put on hold while in school. I shouldn't say on hold, but time for fun becomes a more precious commodity. Sit back enjoy the feeling and revel in your freedom.
Best part of my ASN program, people and the fun we made of ourselves.
Best part of my BSN program - people.
Best part of my MN program people, class discussions, and the trip to England I did as part of my fieldwork (with 8 other MN students).
Common theme I'd say.
Worst part of ASN program - care plans
(at the time I hated them, when I began practicing I recognized that they had taught me to look at the whole picture and not just focus on diagnosis.
Worst part of BSN program - don't recall
Worst part of MN program - loved all of it - wasn't overly fond of one of the quarters of research - but that was due to a crappy professor and her techniques.
Good luck in school! Enjoy it and remember to enjoy the process - you will be sad when it is over...really... usually related to not seeing all the folks you spent so much time with on a regular basis anymore.
