Brilliant one @barrydutton i couldnt agree more thought.
You know happiness isnt like any or every other item one can easily find at the very spot it got lost. If it was so then one would not loose it at that spot in the first place. The world is a big place with over a billion people, and so is happiness, so i think it will be an attempt in futility to try to look for happiness were you lost it.

Moreover, Happiness is the art of never holding in your mind the memory of any unpleasant thing that has passed. In other words forgetting every Unpleasant thing, including the place the place the happiness was lost, and moving on.
