I'm kind of curious what age you are to help answer your question about being an lvn or rn. Depending where you live also should determine if you should try to be an lvn or rn. Usually lvn can do many things an rn could do except central lines or neuro medication stuff. It will take lots and lots of dedication for which ever route you go.
PS. I use to be a nursing student, but now I'm a biology major.
