It has been a few years since I read (and lost) a great article on career progression and personal insight. That article helped me relax into who I am from a professional point of view, but it also challenged me.
I have been in IT for over 20 years now and in truth the first 10 years were not so great (perhaps a story for another time) but it was when I stumbled upon the vCommunity by way of Twitter and then subsequently I attended my first VMUG (in London) which completely challenged and changed my way of thinking and approach to my career.
