I sort of understand both sides of the argument. For me, parenthood is about feeling confident that we can raise good children, and instill values in them that are important to us, and they can contribute to society. At least for me, there is definitely some sort of legacy effect. My last name is going to get passed down with these guys, hopefully for generations, and I take pride in that.
The things like the baby falling asleep in your arms is indiscribable. Their first smile. The first time they call you dada. So many milestones that bring joy to your life. Even bad parents get joy from their children. That much is universal. There's an almost tribal feeling to having your own pod. Wanting to protect them, defend them, provide for them.
It's easier for current parents to compare pre-child and post child life, and that's why we can be so arrogant towards non-parents and tell them that life will not be as fulfilling without kids, because we've experienced both sides. So do I think you will miss out on some joy and happiness? Absolutely, without a doubt. Would the lack of joy and happiness be worse than the frustrations and dislike you have for kids? Dunno. That's the part that I think depends on the individual.
Already a long rant, but I'll wrap up with two times my kids saved me.
Our son was about 4 months old, and I was in a pretty dark place with respect to career, feeling depressed, feeling like a letdown to him and my wife, I was still among the bottom rung of Bay Area stand up comedians, and saw people far less funny get accolades that baffled me. My job was a dead end, crushing, horrible place to work. I was on the verge of a true mental breakdown. The one thing that kept me from losing it was coming home and seeing my new son. He literally saved me from temporary insanity. Got a new job, moved out of the area, and haven't been close to losing it since.
Number 2, I was in a long, stressful application process for a career that I wanted more than any other I'd ever considered. Trained and prepared literally for 2 years. Got through several stages, deep into the process, then did an interview that I know I nailed. I'm quick to admit to my faults, this interview was world class. A heavy bias from 2/3 panelists was apparent at the beginning, but I thought I did well enough where this thing was in the bag. I find out I didn't get it. I couldn't eat for a couple of days. Barely talked. A couple of guys I knew that worked for the same org, were literally cursing their organization because they couldn't believe I didn't get in. For a distraction I agreed to take my 4yr old to the local pool. We're driving and he asks about the "job" thinking it was a race. He says, "Dad, did you win your race." Heck, I hadn't wanted to talk about it even with my wife, beyond telling her I didn't get it. Fighting back tears, I tell him, no, I didn't. He counters with "Did you try your hardest?" I tell him I did. Silence. Then he says, "Well if you tried your hardest, I'm proud of you." I've cried two times in the last ten years. That was one of them.
My kids are the center of my life, and I feel like a better person for having them in it.
