Thinking about how teaching is different.
Some of it has to be that I'm different.  I have learned from every student and situation which has come before this moment.  This knowledge is both a blessing and a curse; while before I would wonder and frustrate about how to help a particular student, and now I know a little bit better, how to help so many students.  Every learning experience for me has turned into a tool for me to use in that same situation in the future.  The frustration comes in my limited human capabilities.  Time, energy and resources.  There's only one of me and so many of them. The challenge is still how to meet their needs with the resources available.  I know more, I can do more. But I can only do so much!
