Hi Windsheer, Paul,
left school with zero qualifications (hated school), worked for twelve years in sales, did quite well, but ended up getting bored. Parents paid for a trial flight for my birthday and I was completely hooked, did my PPL/ATPL's/CPL/MULTI IR/FI ratings and Instructed for a number of years (which I absolutely loved). Eventually I needed to earn slightly more money than Instructing could provide-wife two kids!!
After many months and many rejections managed to get my first Airline job at the ripe old age of 35 and now fly the 737. Please, dont be put off by your age or your lack of academic qualifications. It may seem daunting, but if you have the determination and drive then you will succeed...
good luck.
