When I was student teaching, I had to work, as people many do. In the beginning of our education progam, the advisors advised us not to work during our last year. We all thought... whatever, we have to work. Well, when that last year came around, it was very hard to work and teach. I was a nanny, so I was fine during the day, but as soon as I was done teaching, I had to leave to pick up the kids. I hated leaving immediately and not being able to stay and plan. If you do have to work, try and make your schedule fit to where you can stay at least 30 minutes after! That will help out tremendously and take a lot of the pressure and stress off of "I don't know what I am doing!!"
