I'm still interested in engineering, but now I'll direct that interest toward my teaching, perhaps finding new ways to demonstrate scientific principles, and toward my personal life, making improvements to my house and my brother's catamaran. The bottom line is, you need to follow your inspiration, and if it changes, you'll be equipped to follow it a different way. I think trying to ease into the profession by substitute teaching or taking on other responsibilities which fulfill your desire to be in a teaching position would be your best bet. For instance, you could become a Sunday School teacher or youth group leader or something similar. But because deciding to teach as a profession is such major decision, I would advise getting as many forms of experience as possible.
Teaching takes on many forms and there are endless possibilities.
I have been quite shocked at how much more goes into teaching than actual teaching. Often times teachers cannot focus on givin g students the best education possible when there are so many other things they must deal with. So many times we only hear the difficult parts of teaching and many times I am the first one to write on-line about these difficulties. I feel that students of education should understand upfront the dilemmas of being an educator so that they truely think before they leap. No, it is the greatest Profession.
