Life used
to be simpler, made up of three stages – childhood and adolescence,
going to school and living at home, your adult life, working, raising a
family, moving into your own home and finally retirement. This worked socially, psychologically and economically for many people.
All
of this has changed. In the past, people may have taken a course or
trained in a specific career, such as accountancy or carpentry. But today, it is common for people to have three or more, retraining several times as they move from one career to another.
