I taught high school and college for 39 years. During some 15 years of that time I also helped to develop several businesses up until 2005 when, as the president of a company, I could no longer do both. The time committment became overwhelming. Teaching takes a lot of daily time and energy the likes of which no one who has never taught cannot understand. I weighed the two professions and decided to quit teaching - sadly so - and I'm now developing my fourth successful business. It all depends on where your heart finds its tug.
