Not so much 'change' in my case, more of a 'wobble'.

Started as a retail pharmacist, moved to become hospital pharmacist, a sidetrack to become a COBOL computer programmer in warehouse software, then back to retail pharmacy plus aviation training as far as Commercial Pilot Licence, then back to retail pharmacy when General Aviation went through a downturn, followed by becoming general manager of the family's Commercial Rents business.

In my youth it was common to see people stay in one job for all their working lives. Today it's common for people to have several careers over that time period.
