i came to this conclusion completely independently and without reading any of those works, however i phrased it simpler; people need challenge in order to be happy. if things are served to them on a plate, it means nothing, it's only through overcoming real challenges that we attain happiness.
i am now 100% convinced of this, it is not a theory, it is something built into our very DNA.
