Congratulations on receiving your start date and I hope it all goes well, however, I'm quite sure nobody will ask and certainly do not wait for 'the right opportunity' to tell all about your past experiences. I reckon the Grey Man is the secret to all HM's forces courses. You can still be the best in your class without standing out. So, don't be first, don't be last, never be late, shut up, listen and, above all else, keep your sense of humour.....it will be tested
Well done on getting a date you can use your drill skills to help your team mates who are struggling with it come up to standard. Your team mates can then help you with anything you struggle with too aswell. Just don't go boasting about your six years in the sea cadets which is basically a youth/sports club in fancy dress with a splash of naval ceremony, it's nowhere near actually serving in the RN. Work hard, listen and be a good recruit because of your team player skills and maturity gained from sea cadets. Don't be ignorant enough to think you're a good recruit because you were a sea cadet, because the liklihood is you won't be.
You never know we may be in the same course see you there if you are.
