"I want to learn how to do more extraordinary work"

This program caught my eye, as after working almost a full year at home, I am worried that I don't have an 'A' game anymore. 
I want to learn how to do more extraordinary work, spend less energy doing it, and share lessons learned with my team. One example of my 'B' game is that the number of emails have multiplied exponentially over the year. My in-box feels like an uncontrollable mess.
