My brain can operate perfectly. I don't need to get an epiphany so I can decide to waste my time and ruin my life. You've just been brainwashed with what's always been the norm for everyone.
Nope. I haven't been brainwashed. I just realize that I haven't gotten to the point where I might want to have kids. When I was in high school, many of my teachers would point out that views commonly held by "enlightened" high school students, such as positive eugenics and a desire to limit reproduction as a form of birth control, are held by people who have never had children.
When you are actually old enough to have a child, it's an entirely different story, and your beliefs change even further after you have a child. It's that you don't want children right now, because you're not old enough to be able to take care of them. It's not an issue of mental maturity, it's physical and emotional maturity. It doesn't matter if you think you are mature or not now, you need to accept that your beliefs are probably going to change as you get older and become more mature.
