My background is in IT Consulting and music. I was a Military Musician before getting into IT for 15+ years and then escaping the ratrace and getting back into music.
As an IT Consultant, I needed to learn things. Fast. I was seen as the guy with the answers for all IT related problems and I needed to know at least a little about a lot. I needed to be one step ahead of my clients in all computer related aspects of their business.
I teach music as a peri at local schools and Saxophone privately at a local studio as well as play in several bands.
I've written many books, both physical and digital, mostly under pen names.
Oh, and I'm a qualified Hypnotist as well :-)
