Since you replied as such, I’ll just add: I’ve found that being a parent has made me much better at time management, and as a result my productivity today is higher than it was in my 20s, even though I have less free time. I’ve heard this same experience from many other parents. I’m sure it’s not universal, but if you’re so motivated there’s a good chance you can have a vibrant career and also a great family life with kids.

Cheers and good luck when the time comes :)
