From humble beginnings as "that kid" in school (no one knew about ADHD in those days) a lifetime of formal and informal education, and countless jobs, I have evolved into an eclectic dilettante, accidental technologist, philosopher, dreamer and doer, with a belief that while we may not be able to do all we imagine, we certainly can't do anything we don't imagine.
