Yeah, exactly. If we could go back in time with just a few pieces of information, we could be gods. Predict and invest in every major startup success, write about it and look like a prescient guru, make even more money from speaking engagements, etc.

If you can't take back your knowledge and experience, then it's kind of a boring/null question- you're just back to where you started, and you'll just be affected differently by the roulette of random encounters. (Which could make a bigger difference than we might realize, but there's pretty much no way to predict whether this will turn out better or worse.)

The question is about starting today though, so it's not about going back in time with knowledge of future events.

Still, the knowledge and experience you gained via circumstance are important.
