Today I held a class in Scrum and Lean.
I was able to test some of my learnings from the PSL class in a exercises I made up just the day before. 
The results were almost too good.

Last week I attended the Problem Solving Leadership class held by Jerry Weinberg, Johanna Rothman and Esther Derby.
It was a week full of exercises and simulations and I consumed more knowledge during one week than I usually do for months. 
And I am still digesting it.  This is a early debrief of what I think I have learnt.
