Where to go?

So for the past few weeks I've been having trouble trying to figure out what to do with my life. I've decided to do it all. Let me explain. I've been a veterinary assistant for eight years now and just recently thought about switching careers. The only problem is I like what I do so why feel the need to change it? Part of me thinks that maybe I was meant to do more with my life and the other part of me thinks I'm crazy. I've decided to go ahead and pursue getting my degree in veterinary technology so I can become a licensed technician. After that maybe go on to nursing school. I hope I'm doing the right thing. Only time will tell.
