I often find myself wishing, these days, that I could send a message back in time, to myself some 40 years ago. That little kid had so much promise. His life could have been so different.
I'd say to him: "Trust me on this: Focus on the reptiles or the ancient history. Computers are fun, but they should just be toys; otherwise they'll lead you to a dark and miserable place."
And he'd say to me: "Get lost old man, you're not the boss of me"
