Key question: did Ironport succeed in spite of his family sacrifice, or because of it? It's not fair to recommend spending more time with the family without addressing what the consequences would have been.
Yep..hindsight is always 20/20 when looking through the rose-colored glasses of success. Hope this doesn't give wannabe-founders the impression that they can launch a startup, succeed, all while keeping home life healthy. When you launch a start-up with significant family commitments one of these outcomes is most likely : relationship and business both fail, one fails the other succeeds...if you have nice VC-cushion…
This is something I hate about rich people. You're not a better person because you can take 8 weeks off each year and therefore get to actually know your kids. You're just luckier. Enjoy being rich, go ahead, but don't pretend it actually makes you a better person. Making better choices isn't as meaningful when life hands you all good options and few bad ones.
It's like the rich girl in college who drinks and sluts it in 43 countries before freshman year but insists that, because of her superior travel, she's somehow superior to the middle-class schlub who didn't leave New Hampshire until he went to college. Until you're 25 or so, being well-traveled is an accomplishment of the parents, not the person. (And after 25, no one really brags about it.)
