I am training an Agile basics course right now. I do this about twice a month. It’s the same material which makes it boring for me (I do change some things every course for my joy factor).
But for everyone else on the course it’s their first bite, their first taste if what agile could mean for them. And seeing the light bulbs and thinking and growth happen right in front of me is amazing. Some get so excited they don’t go out for breaks. Instead they gather and talk about how they have already called home to tell their partner they have learned something they want to share. So amazing.
