I think logically this makes perfect sense. There is much evidence for this. For example think of little kids. They have pretty low standards: all they often need to be happy is a new cool toy.
I think it's all about how high you set your standards (or how high they are set for you). For example in a videogame you get to the end of a level and you are all powerful and happy and you think you are the greatest, but then you get to level two and monster become much stronger and now you are very weak and unhappy again until you get better weapons.
So in real life if you live in a small isolated town, you will probably be pretty happy because you are famous in your town and all. Then you travel to a big city and you realize you are a nobody in this world. And the more you know about this world, the high your standards become because you see more and more people who are richer, smarter, more beautiful and better than you in other ways. So you become unhappy and possibly depressed.
But then again, if you stay in your little town, you'll probably be happy all your life.
