I'm in the same boat pal - 28 (29 this year) been a windscreen fitter for the past 7 years, and although I'm fucking good at it, I don't earn the money I used to doing it. If things don't pick up and wages increases/bonus structure etc don't come back then I'm fucked, as everything else is gonna go back up (mortgage etc) and I'm only just scraping by as it is...
But I'm not trained to do anything else, no qualifications, fuck all.
Wish I'd had some forward sense and become an architect or something like that - people always wanna build stuff, and not bad money I'm told. Too late for that now, think it's a 7 year course/training???
