On Desire: Why We Want What We Want

Little is needed to make a wise man happy, but nothing can content a fool. That is why nearly all men are miserable.

—La Rochefoucauld

I am currently reading an e-book entitled On Desire by William Irvine. So I spent the whole holy week feeling miserable. And I couldn't figure out, no matter how much I've tried, what's the exact reason behind this feeling. Though honestly, I already have a hint. And being the person that I am (with this I may mean pretentious), I feel like I'm forever trapped in a world of make believe.
