Yup, and you have to be pretty lucky to hit the nail in the head on your choice of vocation and profession. A lot of people diversify, which is good for the mind, but bad if you have to compete for success. Other people choose very unforgiving fields: want to live a life playing the guitar? Tough luck. Some other people realize they don't like a hobby or job past some point, but turning over decades of skill to start a new path places them in a huge disadvantage. It's not a person's fault to not choose the right career path when they're naturally too young to foresee their future in the field. I personally feel pretty lucky to have chosen computers and technology for my vocation. If, for any chance in life, were to choose anything different when I was 12, then my life would have been entierly different.
