I believe that people can accomplish some incredible things when they are challenged in a positive way. I found this video on the BBC homepage today and there is another one with a guy that just did the 1st double back flip in a wheel chair. It is too bad that so many people focus on the negative side of things. So much more could be accomplished. As always, JMHO.
I think this world needs much less negative and lots more positive thoughts, actions, and goals. We seem to spend way too much time sucking up the negative feedback of the world.
