I’ve actually engaged in such mental masturbation and realized I could rule the world if I could start over as a child knowing what I know now. Unfortunately I think that instead of being a prodigy I’d be a megalomaniacal freak like Stewie on The Family Guy and probably end up institutionalized.
I want to think this is cool, but every time I encounter the premise it just reminds me of “Mork & Mindy”.

I knew there was a reason not to watch all that Nick at Nite when I was young.
If I could start over in high school with today’s knowledge I would settle on one life course and stick with it. I would be an artist. No, wait. I would be a pianist. Or a singer. No, a journalist. Wait, a trumpeter. On the other hand, acting would be a great career. Or I could go into law. Or . . . Come to think of it, it would probably go about the same whether I retained my cirrent (age 62) knowledge or not. Screw it! I’ll stay as I am!
I don’t suppose you’ve ever seen The Butterfly Effect, have you?
If I could keep my favorite form, thus far, I’d say it would be me after the summer of my freshman year: 19 after spending an entire summer in an office job and going to the gym for an hour a day, five days a week.
If I could start over? Hrm…I’m tempted to say about a week before my freshman year of college, as that would give me a chance to alter my course through that particular swath of academia, but considering the way things are currently working out, I don’t think I’d want to mess with it, overly much. I guess I’d mostly go back and re-experience things from there, which I guess would be fun in its own right

Realy?
I never watched the show (I was living in Europe at the time and missed the 70’s and 80’s in the USA) and had no idea my concept was already used.
Will have to catch the show on Nick as Nite sometime…
