I think my wife is turning Zen Buddhist. She said something the other day that just hit the nail on the head. "This is silly, we are doing this wrong. We are focussing all our energy on what we don't have and what we can't have. We are really lucky, we should focus on what we have and remember how lucky we actually are."
Yes, I know - it's obvious, but it's amazing how stress sends you down the wrong path. We are all healthy, the kids eat hot meals, we all have nice beds, nobody is looking to put me against a wall and shoot me. We are luckier than the majority of people on this planet - and it's churlish to dwell on what we don't have. Life can be humbling, and it can be good.
