In our generation, the movement is generally drifting away from a sense of purpose and more towards a sense of personal value. People don't feel the calling where they need to accomplish something before they die as much anymore. It seems to me that people are setting out to be comfortable in their own skin and enjoy themselves.
It has always been my opinion that the reason for existence was to succeed, but only if you can enjoy the trip. Success without enjoyment is the most serious form of wasted life.
