Many people say they wish they had the ability to juggle, metaphorically.
I would really just like to juggle.
I would love to be able to perform on demand that feat of lightness and whimsy. I may just be a collector of parlor tricks and jokes, but it seems to have served me well in life. Always ready with a magic trick, a dance move, or a knock-knock joke. These skills have boosted me to popularity and helped me make new friends quickly.
But seriously, how much cooler would I be if I could juggle?
