We all procrastinate, but some of us do it more than others. Here is a humorous and fascinating TED Talk by a self-proclaimed Master Procrastinator. In his talk he covers what happens in his brain and gives examples of his procrastination.
But his message at the end is meaningful: we really should focus on what we want to be doing and do it before time runs out. After all, we are only here for a limited amount of time.
