Maybe it's different nowadays but when I was at that age (mid 90's) it was rubbish guidance anyway. At the time I wanted to be a racing driver, gun smith or Police pursuit driver ~ in that order.
The guidance I received was rubbish as really the only legitimate job of those three was a Police pursuit driver but she didn't have a pamphlet about that so suggested the Military instead which although I did follow through with to some degree (passed physical tests/sat exams ~ was eligible for REME or the MP ~ my choice) it wasn't the right way forward for me as I liked being close to my family and wasn't interested in seeing the world.
Ended up working my way up in a "Brewers Fayre" Pub kitchen (wash boy/starters & desserts/commis chef/sous chef), then did a Toolmakers apprenticeship, then worked in a car garage then probably another 6 to 7 other jobs before finally finding a career I'm happy with so don't give up as it's never too late to try something new.
My careers advice said I'd make a good mechanic or a doctor...
