Changing personal values

I believe that our values often are like a weather-vane. They change as the wind shifts and that wind might take the form of our varying moods, fortunes, outlook on life and can reflect all the other challenges and joys that we encounter on a daily basis. Perhaps a minority of us can claim steadfast values no matter what happens around us, but I surmise that in most cases, our own values are not immune to our own life-cycles ups and downs and that if they don't change that drastically, their nuances do move around...
