Why don't you want children?

For the people that don't want to have children, do you have a reason?

For me, I don't want children because I feel like I wouldn't be a good mom. Like I'm not trying to be negative or anything I just genuinely feel that my personality wouldn't be a good fit or like... I wouldn't be a good role model? I don't know the word. I just think that I don't have the ability to raise a child properly and that they wouldn't turn out the way I had hoped or would be a bad child or wouldn't have manners. I'm not saying I'm a bad person or would be a bad influence, I just don't know how to raise them. I also don't like when they are young because most children are bratty.

Also, other factors are the community and the environment. I personally believe that the future seems bleak and I don't want to raise a child that will have to live in poor conditions. People believe that we will live for a long long time but I believe we are going to run out of time soon. An example of this is the rapidly declining water and global warming. That stuff is happening a lot faster than most people think and it doesn't help with a climbing population. Then the community... well speaks for itself. I don't want them to be influenced by others and it seems like people get worse with every generation so I don't want them to end up bad.

I would like to have a child if these issues didn't exist, but chances are, I won't have a child. Oh, and also my main goal in life is to travel, so I would either have to give that up or save a TON of money, which would mean I wouldn't be able to go to all the countries I wanted to go to.

P.S. Do you guys think people truly consider their child's future? Like how I considered the community and environment, I feel like other people don't take that into consideration and have a child based on their own selfish needs which really irritates me when I think about it. If you made it this far, thank you so much!!
