Yesterday on the chairlift I was chatting with a man who had studied at Berkley to get his PhD in biochem engineering. After spending a bit of time in the hospital he decided he hated the hours, and he hated the stress. He left LA, and moved to Taos to teach skiing, become a contractor, and love his wife. I tell you this story only to show that you don't always need hardship to realize that your job doesn't always run parallel to your happiness. Some of us come to realize where their happiness lies through self-discovery and reflection; and others need something as drastic as being laid off to kick them in the butt.
I don't have my quotations journal here, but if I did I'd recite accurately a quote from somebody I could give credit to. But in the mean time, consider this:
"Misfortune is like a knife.
It can be a useful tool, or cut us.
It all depends on whether you grab the handle or the blade."
