"You have little kids for four years. And if you miss it, it’s done. That’s it. So, you gotta know that. It’s, you know, lots of things in life, you don’t get to do more than once. Now, obviously you can have more than one child, but all I’m saying is, that period between 0 and 4, 0 and 5, there’s something about it that’s really, it’s like a peak experience in life. It isn’t much of your life. You might think of it as a long time. But it’s not that long. Four years goes by so fast, you can’t believe it. And if you miss it, it’s gone. So you miss it at your peril, and you don’t get it back."
