Also me when I was young. The only downside was a more realistic (not mature) view of the world. This has lead men to not doing things that would have been mistakes easily forgiven at that age. My real life was a bit boring (I’d carefully select friends, keeping myself out of troubles) because my imaginary life was exciting enough). Apart from the knowledge I acquired, the upside is that I can keep track of a lot of abstractions needed for problem solving.

Whoa, same here! I too had a realistic view of the world, but at the same time was super naive. And the entire phase of teenage rebellion did not exist for me, kinda weird when I see it mentioned everywhere all the time. And "boring" was and sometimes still is the way to describe me - too cautious, and not enough spontaneity.

But I don't think I'd change anything even going back. Too many benefits...
