For the time-challenged? Me, in two words: Positive force.
Still reading? Good! I'm 39 and have zero qualms with turning 40. I firmly believe that life is to be appreciated, enjoyed seriously, and seriously enjoyed.
For me, work is a joy that takes many forms, not merely 'the office'. Every aspect of life requires effort and attention. Hard work, then hard play. I want 'the most' from every area of my life. Complacency has no place.
My greatest joy? Shared experiences. Life is not meant to be a solo endeavor.
