It's nothing that complicated. Try having kids and staying as focused on ANYTHING as before you had them. And as your kids get older and you have to worry about more things like their education, health (vaccines, diet, athletics, etc. all rolled into one), finances (well, not so much in Fed's case).... it only gets harder.
I don't even think about starting new businesses anymore now that I have kids, just maintaining my current business interests and giving time to my kids is full time as it is.
It's a testament to his pure talent and drive (even fading drive) that he still is near the top of the game.
