In the first quadrant, there are people who are in the most desirable state - they know there is a ball to be on, and they are on it - that makes them a "1" - they are an ACHIEVER, on top of their game, and truly "on the ball"
Now, being an achiever does not just mean achieving some larger than life activity like climbing Mount Everest. Achieving means accomplishing. Achieving means completing. Achieving means seeing something to its successful end. We attempt to achieve things large and small everyday. Some things take months, maybe even years, to achieve, but we keep making positive progress towards those goals.
