Hi Pam,
Those are snowshoes on the wall. This was up at my cabin in the northwoods of Wisconsin.
Learning curve for writing? I love writing educational stuff. It's in my blood somehow. My first book was published in 1995. The title had nine words. I've since learned that two word titles sell better than 9 word titles. ;-) Advice? Read a lot. Write a lot.
Yes, I was there when the first scrum master course was scheduled. Ken Schwaber came to me and asked if he could borrow one of my classrooms. I ran a training company in those days and I had several classrooms. I didn't attend because I had somewhere else to be. I also thought it was a dumb idea. Who would ever want to be a "Certified Scrum Master"? That shows you how much I know. ;-)
