Like many other walks in life teaching can run in the family. I know many teachers whose parents were teachers and whose children are teachers. I also know many teachers who come from families where there are no other teachers too. I got into teaching because the field hockey team I played on at weekends was composed almost entirely of teachers. It was a mixed team, 6 men and 5 women players and we were called the Jackdaws. At the time I was a Quantity Surveyor but didn't really like it. So I quit my job and went off to college at 21.
There are lots of reasons why we become teachers. Some get into it because they love being around children while others want to change the world. Some like the idea of the long summer vacations while others love a particular subject such as math or english. There are those also who like the idea working with specific populations of students such as English language learners or students with special needs.
Whatever the reason, it's important to explore that reason and there's no better way than getting classroom experience in a public school on the "other side of the desk". In my case, I certainly didn't become a teacher because all teachers like field hockey, but being around teachers and hearing them talk about their jobs sewed a seed of curiosity that I followed until I had gained enough classroom experience that I knew that was what I wanted to do with my life.
That's my daughter Marie and son Andrew in the picture about 4 years ago trying to stop me from watching a St. Mike's women's basketball game. My daughter is now getting her graduate degree in special education at St. Mike's and my son works one day a week in Alliot, the college cafeteria. Although he graduated H.S. this past summer, because he has a disability, Down Syndrome, he has four more years of H.S. eligibility during which time he will work part-time jobs such as serving food at Alliot.
