Have you ever heard the expression Ignorance is bliss?
It applies here.
Bob, is a very intelligent man. He works 65 hours a week for a fortune 500 company in a very esteemed role. He expects the deal he's been working on for months to go through when all of a sudden the deal falls through. Bob is crushed.
Joe, is below average. He scraped through high school and does hard physical labor 50 hours a week. His only expectation is that he'll work all week and have the weekend off to spend his meager paycheck doing something with his family. His expectations are met every time. He doesn't expect much, but he is happy.
It's all interpretation. Bob would think Joe is poor because he doesn't make much and doesn't expect much. Joe would think Bob is poor because he makes 6 figures a year, but can't even think of his daughter's best friends name.
Yeah, I went off on a tangent and talked about irrelevant crap. But, I didn't expect this post to make as much sense as it did.... so I am happy ;-)
