I'm hungry for knowledge. The whole thing is to learn every day to get brighter and brighter. That's what this world is about. You look at someone like Gandhi and he glowed. Martin Luther King glowed. Muhammad Ali glows. I think that's from being bright all the time and trying to be brighter.
To me living in the present means being aware of your conscious choice to focus on the past present or future - it is not necessarily having to focus on the present.
