To me, this photo epitomizes the concentration and focus that comes so naturally to Abbott (and most children) when he's doing something that really engages him.
Here's the excerpt Abbott will read today at school from the book he's presenting (the photo above is his project about the book):
"Al had never been so disappointed in his life. He went home and set up his laboratory again with the encouragement of his mother. He continued to experiment and tinker with every gadget he could get his hands on. Usually his experiments did not work - but he always kept trying." - Young Thomas Edison by Michael Dooling.
