Here's my two cents worth -
Part of the answer lies in describing the glass that is half full/half empty - both are true but which description you choose belies an attitude. As a Christian, I'm always (don't infer that I am "always") to be thankful for my state of (family I'm born into, land of birth, time in history of our life, social status, wealth (or lack of), etc. etc.) As we go through the list, my emotions rise and fall - some very positive, some no so much. Jesus stated that if we have food and clothing we are to be greatful - maybe the milder climate in Israel didn't require housing as such. As part of the middle class, the onus to expect a higher standard of living by sweat and smarts is part of my psyche. I am part my culture. I am hoodwinked, by my own volition, to be the upwardly mobile part of society. Alas, I have to admit that after having a great start and being the envy of young america things went wrong - ugly divorces in the family, untimely deaths, conflicts, bad advice, not going with my gut, etc., etc. 15 years later, it looks like things are starting to "get back on track" so to speak. I don't pretend to think I've got it all figured out or that I have any sure guarantee what my worldly future holds. I've been humbled by things that were out of my control and I have had to learn to walk in God's grace to keep my sanity and have hope for the future. Peace and blessings in Jesus Christ.
