Happiness and Maslow's Hierarchy of Needs

I think when I think about happiness, I often think about Maslow's hierarchy of needs. You know, the needs lower down in the hierarchy must be satisfied before we can attend to the needs that are higher up. And only when we achieve those bottom components of the hierarchy are we actually able to achieve self-actualization and feel completely happy within ourselves. This model I think can explain why happiness can be so difficult to find and why it is sometimes not just elusive, but actually quiteQuite difficult,. you know, it's really hard to be attending to every single aspect of this day in and day out.
