Someone I met today is a teacher.

She's been working for a telecom company for about 15 years, but teaches on the side. She's currently teaching excel classes as a number of different places, and a bunch of different things.

"What's your favorite subject to teach?"
"Favorite subject? Most interesting was design thinking... While I enjoy teaching scuba diving, I think disaster training is probably one of the most fun."

This woman was very unassuming. She's much older than I am, maybe in her 50s, shorter and a little plump. Her blonde hair had white mixed into it, and her blue eyes were hidden behind her glasses. Based on her looks alone, I don't think you would have guessed that her interests were so broad.

"Why do you like teaching?"
"I like talking to people. It's a nice break away from managing computers at my workplace and is definitely more fulfilling. Seeing people's faces light up when they get it is so unique."

I enjoy talking to people who genuinely enjoy whatever it is they do.
