Being a teacher is a profession, and like any other, it requires dedication and learning. It's a wonderful, powerful profession that has a significant impact on people's lives. I started teaching in 1986, about 40 years ago, and I've always felt fortunate to have had this job. However, being a teacher in the 1980s wasn't the same as being one in the 21st century: the world has changed... and will change in a few years. The job isn't easy. We work with adolescents, people with a different worldview than adults. Conflicts arise. You have to be aware of them and be prepared to face them and, if possible, resolve them.
