How do I become a teacher?

I have learned more about how to become a teacher through out blog entries. There are a couple of reasons for this. One I am beginning to learn how to use technology to its fullest, and with the way kids are attached to technology this could be a very useful, if not mandatory, skill. The other reason for this is that each chapter that we have to blog about has something that we will need, and by blogging it the information will be there until we need it. The one thing I would like to know more about is what goes into a good lesson plan. The reason for this question is because I have an anxiety that I will just freeze or have too much time left after I've done what I felt would take up the allotted time.
