I came across this picture and it really speaks a lot of things to me, An art must be something that should communicate something to the viewer and this really tells me happiness is not always getting everything but appreciating that something we are having, The truth is if we are always happy for having or getting everything, you might not get something.
Happiness is a relationship that is built inside us. These children in the picture that have everything but I can see they happy because they have something and that is the river they are playing inside..
forget about your swimming pool... We are happy and nothing can stop that from happening.
