Children are big plans. You don't get to pick sleep, and you don't get any other big plan.
Fortunately Children for all their work are rewarding. You won't grow as much at work. However you get to see and do many interesting things in return. If you are lucky you can get your kids interested in your hobbies (this isn't that hard)
One reason to never become CEO: they travel 200 days/year and thus don't get to see their kids much - at less than $10 million/year they are grossly underpaid for the time away from family.
