Why not?  I have wanted to be a teacher all of my life.  Of course, I do know that I do not want to spend the rest of my life in a classroom. 

I have had other jobs that allowed me to teach, while not a fully accredited teacher.  For example, I worked in a maximum security prison in my early twenties.  This was between several attempts at earning a college degree.  While I was not a teacher, I would like to think back (and can on one specific instance) that I taught a few people how to act or treat others.  (There is a story to this, but I do not feel that this would be the best place to share this story.)  I have also worked in a group home for children and adults with moderate to severe disabilities.  Of course, I think I learned more at both of those jobs, then I probably taught to anyone I came into contact with during those experiences, but someone was teaching. 

The point that I am trying to make is this:  everyday an individual encounters other people.  There may be other individuals that will learn from the first individual or the first individual may learn something from all of the others.  I learn everyday. I think everyone does.  I also, regardless that I am now in my own classroom, still teach (sometimes without even knowing that I do.)  So, why teach?  To learn, to grow, to become a more productive person in some manner.  I truly believe that everyone can learn, it just takes a little effort to pass the knowledge on to others. 

I have learned more from my students this year then I would have ever imagined.  I look forward to returning after Spring Break (and then testing) to teach what I have learned (blogs, podcasts, webquests, etc.,) to my students and then learn from them when they create their own part of technology.
