Kids are absolutely post main story content. You better have your life in order and your aspirations met because you’re about to do some serious compromising when you throw a kid in the mix. I think one of the best decisions of my life was to fulfill my needs before having children.
I don’t know about your situation but it is okay to not have any aspirations. I had one aspiration which is kind of a cop out because everyone wants that. I wanted to be happy with my life. I figured if I was happy I’d figure out what I really wanted to do. Once I figured out how to be happy nothing changed, I didn’t get some magical desire to do more or be more. I was happy and I was happy being happy.
Don’t put so much pressure on yourself. If you have aspirations you’ll probably feel them, and if you dont feel them then maybe you don’t have them. There’s no set way to go through life, some people have aspirations and some don’t. The only good life advice I can give is that best way to go through life is doing whatever makes you happy. It’s your life, don’t live it for what society expects you to live for, don’t live it for what your parentst want you to live for, live for yourself.
