Would anyone else have also made a different career choice if they had been diagnosed earlier?
Depends upon how much earlier. I am thinking if I was a child when I was diagnosed there would have been adults in my life trying to manipulate and direct me in a certain direction based upon what they perceived were my deficits and strengths. Once I was in my 20's, I was already on a path that probably wouldn't have changed had I been diagnosed at that time. On the other hand, I would have been much more aware of myself and might have changed what I have said and done in my life that might have influenced my current situation and career status,...I don't know.
But,...if I had access to a time machine, knowing what I know now, I should have managed my money quite differently, and invested in all the new, innovative companies and products that are a part of our life now (cell phones, computers, internet, on-line shopping, Bitcoin,...a bunch of things). Then, I would be a "bazzionaire" and I wouldn't be working for anyone right now,...I'd be sipping drinks in my private floating Tiki hut in the Maldives.
