I think my philosophy has evolved over the years. I started teaching almost 15 years ago and I've learned that how one student learns is obviously much different than how another student learns and so I've had to figure out how to get through to people honestly without hurting their feelings - which is no easy task just in the scope of being a human being, much less in the classroom, but which is something that is more important to me now than it was when I was 30 - and to show them a path to improving.
