I was really inspired by this article, http://jamesclear.com/marginal-gains. It speaks of how, in 2010, Dave Brailsford took over the British professional cycling team and by making just 1% improvements, he help lead the team to multiple victories.
I was often timid to try new ideas because of the drastic changes required. But when I looked at implementing small changes, and breaking larger chances into smaller chunks, I have found myself more confident to give things a try. A bunch of small changes can really add up.
