Future

So right now I am feeling super confused. I feel like I want to go into teaching but the thing is there is a part of me that i just dont think has the passion for it. Am I really wanting to go through another 3 years of schooling to do this. Again I am faced with the thought of taking some two year program and being done with it. but then again that only puts me a year a head of the game. I don't know I guess its just worry, that what if this isnt what is going to make me happy for the rest of my life. Sometimes I think I just chose this profession because I felt like the pressure was on to make a decision. So here I was and i thought why not teaching, and touche why not teaching, but more importantly, Why Teaching?
