Those who can't do...teach?

Well here I am. About to begin my 5th year of teaching. I'm excited because I just got transferred to a new school (at the beach!!!!). This is a big deal because my previous 4 years of teaching have been at a tiny, urban school in town. I have many stories to tell about this school. Stories that, as I reflect back on my first years in the teaching profession, I will post here on this blog, which is the true purpose of this blog. However, this post is more of a reflection of what is to come.
It has been said that those who can't do, teach. Well, what if you became a teacher because you didn't really know what to do. And what if the teaching experiences you have had thus far, have been those of sheer terror. I'm really quite surprised that I have had the resolve to stick with this profession for 4 years. And, to be perfectly honest with you, I probably would have quit had it not been for the lovely transfer to a wonderful beach school. Of course there is a huge part of me that is very reluctant. How different can it really be? Aren't all kids pretty much the same? Do socioeconomic differences really make a difference? I ask these questions because if I have the same type of experiences at my new school then teaching is not for me. And if teaching is not for me, then what is?
If you can't teach, what can you do?
