Just the word Dedication brings up some strong imagery. What drives us to devote ourselves to something to the point of it hurting you? What would cause someone to do muscle ups until their hand bleeds?
The other day I did that exact thing, at the bottom is a picture of my hand taken shortly after. Only recently have I become strong enough to perform muscle ups and I decided to stay late one night at Apex Movement and see how many I could get before I would stop. I also made a little bet with my friend Justin who was sitting by watching. The wager was that he would buy me a beer if I could make it to 11, I pulled out 21!
I guess dedication and motivation could be best summarized as something tangible. Also beer.
