I've been nerdy since before it was cool. Prior to working at Microsoft, I was a technical exam question writer for Grandmasters and contributed to about a dozen exams from Windows 2003 to Office 365, as well as writing Microsoft Official Curriculum for System Center Configuration Manager and App-V.
I also wrote a book once.

Go. Do it now. I've got 5 kids to put through college.
