Someplace, or some time? 1971.
(I don’t know that I would go back, but I do wish that I knew then what I know now. What do I know tomorrow, a year from now, forty-six years from now that I’ll wish that I know now? How much of it do I actually know but not know that I know? How many of the pieces of the puzzle do I have, but I can’t quite put them together to get the big answer? What if the big answer is that there isn’t any big answer?)
