As someone who is 34 with two kids (toddler and newborn), I completely agree with your comment. My wife and I had difficulty having kids, or we would've had them sooner, but I completely agree with having kids before 30. My energy is still solid, don't get me wrong. But it doesn't compare to energy in your 20s. People think too much about the financial aspect. You can continue building and growing financially even with kids, you just need to be smarter and more disciplined. A lot of people use the financial argument, but I think more and more, it is only a cope for not having had kinds sooner. All my kids will be in their 20s when I'm in my 50s; not bad, but having kids in your 20s is the way to go.
