Chris, thank you for your feedback. I've given the chorus more thought, and still feel it need not be so specific. I perceive the boy (when the man was a child) as being quite young, in his pre-teens, and a boy's dreams at that age are not likely to be realisable anyway. (He might have wanted to be Batman, or a super-hero, or an astronaut, or whatever.)
I have, however, adjusted lines 3-5 in the chorus to - I hope - provide a sense of the feelings the boy might have had about his future. It's clear the man feels he has forfeited the sense of joy of discovery, the possibility of making new choices, and pursuing other opportunities. I think people will be able to relate to that.
Thank you for the nudge. 
I've also changed a word in V3 (from 'uppers' to 'caffeine').
Donna
