I think my opinion on children is going to bury vastly from the vast majority of people here and the simple fact if it comes down to, I see what my friends and family spend on their children and holy shit I’ve been bringing a life into the worlds, beautiful thing, but isn’t it a beautiful thing to be able to live a much more comfortable Life yourself?
I think that since my DNA managed to reach 2025 year, it's my duty to leave someone who will continue the existence of my DNA in this world. It's probably not the most beautiful world but I don't want my to be the reason of the disappearance of my DNA.
By the way, much more comfortable life can be achieved if you have a good wife who also works and doesn't yell you to buy things for her all the time. You pay the rent together, you give gifts to each other. In the best case, both of you achieve greater things together and start your own business and so on. Then you two grow kids together and enjoy the life. In your 20s and 30s, it might not make sense but you want to live in your 40s and 50s and more, right? When you are older and live alone, there is no one at your house who loves you and hugs you, is a terrible life to my mind.
Why do we study in our teen ages? Because we want to have a good future, instead of playing in the yard, we do things what we love (studying math) for our future. That's why people marry in their 20s and 30s, to have a good future.
