Happiness makes for a cruel master
Comfort has become something of a secular god in recent times. Its perhaps better marketed twin, happiness, is frequently stated (by people who I often admire) as the ultimate goal in life. Find your passion, find what makes you happy and go make your dreams happen etc.
But I do find this line of thinking to be somewhat limiting. Because all of us know deep down that happiness is forever fleeting and is so often here one moment and gone in the next.
