And also, people change a lot. People think differently and have different values, needs, tastes and dreams, from decade to decade but mostly from childhood to adolescence and then from mature work life to retirement when values change dramatically. Once in a while, I look at my journals of 20 years ago: What I was considering "success" then was mostly the rat race: go faster, always faster, go further ahead than the next guy, get that VP title before my friends get theirs. 80% of my values were materialistic.
