Yes. Being a "mature responsible adult" isn't worth the effort to me, therefore, I choose to keep the mentality of a child/teen because it makes life more fun for me.

I mean, what is the point of being mature and responsible? How does it benefit me? It would require a lot of effort for me to change so is it worth it? I don't think so.

More responsibilities and more things to chain me down isn't good. One can make an income these days without being fully "mature", especially if one is intelligent and capable of critical thought. One can find romance without being "grown up" even if it might be harder. So tell me, how does it benefit me to change?

It benefits society far more because society wants you to be the perfect good little slave working your butt off your whole life as little more than a cog in a machine so they can milk you for what they can and dispose of you the moment you outlive your usefulness either by getting sick or old. Humans are conditioned to be good little servants by being told they need to go to school, then go to college, then start a career, then get married, then have children, then grow old and retire and those who want to live life their way even if they don't act like society wants them to are labeled as "childish" or "selfish" and I for one, would sooner die than take the path society wants me to do; I am my own person and if they don't like it, they can go screw off.

If anything, people with a more childlike mentality get more out of life. Life is too short to be unhappy for other people. I will live life with my "immature" mentality having more fun, getting more out of life, having more sex, and having less struggles than the so called "normal" people.

That is all
