JGab- Growing up I was in the same situation as you; from the age of 6 onwards I had to put up with people telling me I'd never be a military pilot due to my shortsightedness (-3.25!), if I had listened to them I'd be working in an office or running around freezing my arse off with the Army.
Instead I told them where to stick it and am now in the process of completing military flying training- not a fast jet pilot yet but a lot closer than what other people told me I would get!
