>>Not in the "Ugh, fuckers" way, but in the "God damn it if I knew then what I know now or at least listened to the people who did know, I could be that ultra successful young hotshot! I had all the opportunities and I didn't take them for various reasons. Grargh!"

Eh, the types of success we envy is mostly a matter of luck. Being born to a family with means and connections, being good-looking, being at the right place at the right time, etc.

Obviously if you actually knew back then what you know today, you would buy lots of bitcoin and Tessa stock. But in terms of "soft" knowledge, I'd say you would probably end up in a similar place.
