I’m not unaccomplished, by any means (nice job, married to hs sweetheart, big house, nice new cars, etc), but I genuinely felt like I wasted my life before having a kid. We had our first at 36 and we’re about to start trying for a 2nd at 38.
Which is to say, while it’s hard, it’s one of the only things worth doing in life. IMO, obviously.
(For the record, in our 20s we were the “no thanks” crowd, I changed in my 30s and my wife took an extra 6 years to come around)
