A mid life beginning?

A typical life can be described in the following phases,

0 - 15 – Growing and learning phase
15 - 30 – finding a partner and experimenting phase
30 – 40 - settling down and reproducing phase
40 – 50 – regenerating health, wealth and security phase
50 – 65 – reflective phase
65 – 85 – watching the life your offsprings


I am perhaps half way through my life span. A time most people start to worry about midlife crisis, and here I am just beginning

To learn to speak, (a new language)
To learn to write, (creatively)
To study, (Masters in Interaction design)
To learn to drive, (on the other side of the road)

In other words, I am just beginning to rediscover life all over again and believe me I am just as nervous as I used to be at 20. I am wondering if this is a sign of failure or hope.
