And I sure as hell don't think Zuck is "better" at tech or being a hacker than I am. Luckier, perhaps, but not better. I guess we'll see.
Also, I was married at 19, and a year later was a father. By 24, I had two children with a third shortly thereafter. So I definitely had the whole "lots of responsibility" thing dynamic, and while I do agree it slowed me down relative to what I could have done if I was single, it wasn't fatal and didn't stop me from learning, or becoming good at what I'm doing.
But again, I'm probably an outlier.
