Well.. Yeah, why not? If person x is happy, it doesnt have to look like that for the other people.
For example, I am happy just the way I am, I dont have real-life friends, I sit infront of my computer most of my time and I probably look pretty damn miserable in other people's eyes.
But then again, what is this "greater happiness" youre talking about...?
If its something that should make you happy, why to even bother to reach it since it will just make you sad in the end when someone takes it away from you.
