My class is different. They have to qualify, and have to ask to get in. When they leave, they are giants who can mike drop things that 99% of adults cannot do. (And they have a blast, while learning.) If it isn’t fun, they are not going to learn. The secrets to herding cats is either a string or a laser light.
I have a little nicer watch. Accurate to the second and water-resistant to 100 m. My OCD is smiling, inside.
