I waste my time away, drawing pictures in the sand

Today I went in to Dublin Castle and there were sand sculptures on display. They are pretty awesome looking and really detailed. All I could think was how I can barely draw a smiley face or stay within the lines and how I try to avoid all artsy things if at all possible for fear of looking like a fool for being so un-artistic (is that even a word?). Anyways, I wondering if the sand sculptors make any money for all their time and effort or if the government fund them to play with sand all day or if they do it as a hobby? I mean I only wondered this for a second, the truth of the matter is a couldn't care less, I just don't 'get' art.
