Turning 40 is often a big symbolic point in one's life. In the 20s we feel we can do anything, but as the 30s progress we become more mature emotionally, and in terms of work tend to focus. These two things combined: emotional maturity and career focus, often produced an explosion of self-purpose in our 40s.

This is the period from ages 60 to 90 in which many people have a new sense of freedom, kids grown up, retired from formal work etc., about their possibilities. They can either crown a career, start something new, or launch themselves into a meaningful social enterprise. A phase of life that was once seen as an end can now more accurately be enjoyed as a beginning.

People race to achieve everything by a certain age in their life, be it 40, 50 or 60 - but with increasing life spans 50 or 60 might be just the beginning of a new career, or just the point when you begin to get into your stride. There used to be a syndrome of me retiring at 65 and then dying not long after because their life was stripped of meaning, without their work. But these days you may live another 20 or 30 years beyond 65 so you have to figure out where you can make another contribution.

The more choices we have, the greater the need for focus.
