Part of this living out 100% concept (which I need to coin a new term for) is that when, through observation, you recognize you could be doing something better, you figure out a way to do it better, rather than getting down about the fact that you aren't already doing it better.

I should be very happy when I discover I'm not doing something as well as I could be, simply because I've discovered it... That is a new opportunity for me to improve as a human being.

There's no way for us to change the past, but there is something we can do to affect our future.
