As for careers advice - you never know where life's twists and turns take you.....as in....
Merchant Navy engineer cadet then officer, degree course, redundancy, NHS Estates officer, redundancy threat so retrain into HR, HR Clerk, NHS HR adviser, outpatients service manager, stressed out move to IoM, Sub-postmaster, HR officer in Soc. Services, Office Manager Youth Justice (Young Offenders) Team. And I'm not quite 54. So career planning didn't do much for me, did it! I would still be at sea if my initial plan went through, or maybe lecturing in Marine Engineeriing. Ho hum.
After all that , only the first and last jobs provide job satisfaction.
