First off so, your parents are part of the starting conditions obviously. But I think I read that from twin studies there are indications that parents does not help all that much.

In the U.S. just focusing on education can be bad, if you pick the wrong one you just get a giant student loan and not much else.

Finally, even though starting conditions and luck are extremely important, you can’t do much about them. So hard and smart work is still the best option to improve. Going back and giving itself better starting conditions is not an option.
