Nursing Student ADN considering going for my Masters

So I am still in my very first semester (again) but I'm doing I think very well. I am pulling B's in my classes. I was just wondering how long it would take for me to go and get my masters? If I do it one step at a time. (PCT, Nurse, Bachelors, anything in between, Masters) That seems to be making things go alot smoother for me. I got all of my prereqs done for the ADN program. Then I took a PCT course and got that done. Then I was accepted to my ADN Program at a Community College. And I am currently working on that. Once I get my RN license I would like to work and go to school maybe online classes, or something. I was just wondering everyone with a Masters, how long did it take? I want to be a Nurse Practitioner, maybe even a nurse educator.... Any tips suggestions? Thanks everyone.
