Uninterrupted me-time might largely be a thing of the past, but you'll learn how to fit stuff in around watching your kids and spending time with the wife: a few minutes here and there can still add up over the day (especially if you don't get to sleep).

I remember, shortly after our daughter was born, telling a friend of mine that it took me several hours to get through a ten minute YouTube video.

We got really lucky with a baby that slept clear through the night from very early on.
