Happiness as The End

The concept of happiness as the end of all that we do is understnadable. But what do we call the moments between now and the end? In life there are many things we do to make ourselves happy but what about the things we do, not because we want to, but because we have to? People who work jobs that they do not like are not performing an activity that makes them happy. The end may be that they are paid, thus affording the ability to continue to live, but are they truly happy? When we do things in life that do not make us happy but allow us to continue living, is that ultimately achieving a form of happiness that we are unaware of? With this interpretation, it seems like the moments in life that we think are not happy, lead to a greater understanding of what life is, and that is a happiness in itself.
