I’ve heard similar, the quality of the time is more important than the quantity.

Before my boy was born I might not get home until after 8, rarely before 7. When he was born I made the decision to always be home for family dinner. And do you know what, my work didn’t suffer because I wasn’t putting in those extra hours. Knowing I had a hard out every day helped me focus on getting the most important tasks done and letting the busywork ride.
