> Maybe you don't need to have kids, but you do need to find some kind of full filling activity, outside of start ups. It will help you focus when you aren't doing that activity.

This definitely sounds true.

Taking it a little further ... startups are all about freedom and money.

As time goes by, those count less and less for me personally. The freedom you get comes with extra responsibilities, and you really don't need that much money to be happy.

But there's nothing like a kid coming into the picture ... a little boy is on the way and I want to be there for him in every possible way, never miss his first steps and provide him with all the financial support he needs to succeed in life. Suddenly regular employment doesn't sound so great.

Entrepreneurship is exhausting, life itself is exhausting and for the long term you need a motivator outside of feeding your hungry ego.

Having a kid is extremely focusing. I had an 8 month old at the start of YC. There was nothing else. With my second's recent arrival, I'm focusing a lot on what I want to do with my time.

Good luck being able to plan that, we tried to have two kids in two years but nature intervened; my wife became pregnant within two months of trying with our eldest and no matter what we tried it took four years for our second.

0 kids in 50 years: even better than "best"

Two Kids, In Two Years: Best.
