I just graduated from a very reputable nursing program in my area, passed my boards and accepted my dream job in a world renowned hospital on a floor I wanted and will be starting in a few weeks. I should be unbelievably happy right now because I have everything I wanted, but I'm not. Part of me didn't want to get this job so I would have an excuse to travel. Spend a year or two working on Native American reservations, maybe be a nurse for the peace corpse, do some volunteering and take advantage of being 22. Now that I've accepted the position at the hospital I feel like I'm losing that part of me that is adventurous and fearless and selfless. I'm afraid that I will settle down in a job and city and never again be able to do these things that make me who I am. I am not trying to sound ungrateful for the opportunities I have been given, but I just need to know if anyone else has been in my situation and how they managed to leave the hospital life to work in those types of community settings. Any thoughts or advise?
