To be honest, your heart really has to be in it for education to be a worthwhile profession. I just completed my student teaching in a kindergarten classroom and it was the most rewarding and exhausting four months of my life (I also worked part time while doing this). If you're looking to go into K-4 like you stated, you really have to put forth a good deal of extra effort to make the lessons you do interesting, creative and educational so that you can keep the students interested and their participation level high. Education isn't exactly the type of 9-5 profession either so you have to keep in mind that you will almost always be bringing home work because your work day doesn't end when the bell rings. You definitely don't chose to be a teacher because of the salary
On a separate note, isn't a masters required to teach at the college level? I was always under the impression that most professors at universities are required to have a doctrine to teach whereas adjunct instructors get paid less but are required to have a masters. I'm not sure of the degree required to teach at the jr. college level.
