How do I start thinking like a teacher?

This one is hard for me because after going to school for 13 years its hard to switch gears... and in every other class but this i'm still the student that is learning. I know that it's going to take time but I need to start looking at the material that is given to me and see how I looked at it and think about the other ways that people could look at it and remember that... I need to work in groups to see other learning styles and pick up tips on how different people "get" things that are different then me.

(This is going to be the hardest for me)

Questions: 1 How many times can I take the Praxis? Do I pay each time?

2 If i'm not getting through to a student does it mean i'm not teaching the right way, and not being sucessful?

3 I know what I like, but how do I not bore other students that I'm teaching?

4 I know it will only take expierence, but when I first start teaching i'm nervous that students will spill their guts becuase i'm young and I want to be there for students but I want them to know i'm not their "friend"... this is a concern of mine.. still being the teacher but being there for them to.
