Are you the smartest person you know???

34 year old single self made small business owner. Always in a good mood and live by the philosophy "no bad moods"! I'm a work hard / play hard kinda guy and stay focused on achieving success, both with my work ventures and with my hobby's (competitive nature - from being an athlete my whole life i guess). I like to think that I am pretty good at most things. Friendly when playing games, but also enjoy highly competitive environments and challenges. Want to challenge me? What are you REALLY good at??? :-)
