When I was taking an Art History class on Rembrandt and Rubens the teacher told us a story about Rembrandt and how he would sneak into the Sisteen Chapel and sketch Michelangelo's work. And then he would tweak it just enough and call it his own. Michelangelo got so angry he actually had the chapel locked and set up camp inside.
I always found this story profound, because we all do it. We read something or see something and think "Oh what a great idea!" Then we take it tweak it just enough and wallah it becomes our own. I can see why inventors are so protective of their ideas. They don't want them stolen. So this is my challenge. I challenge you to come up with one idea that is your very own.
