Need some advice about what happens after graduation and NCLEX?

I'll be 21 when I graduate in May and so this is all very new to me. I don't really know what direction to go after I graduate. I currently have a job as a nursing assistant on a pediatric med-surg floor and they have assured me that I could more than likely work as an RN once I graduate. The problem is I really don't know if I want to work in peds. As much as I hate to say it, I feel like I should really go to an adult med-surg floor and get a solid foundation of experience. If it's one thing my instructors and professors have taught me it's that if you work at least 2 years on a med-surg floor you can work anywhere. So basically I have no clue what I want to do in nursing, sort of want to do peds and just need some advice from you wise "been there, done that" nurses Any advice would be much appreciated!!
