In maybe a non-sensical way, it seems like having children is my best remaining contribution to the world. Maybe I can make a slightly better version of myself and teach him how to be a better person than I was. Otherwise, it seems like what I have learned and all the knowledge I have accumulated will essentially be wasted. What was the entire point after all? If I don't pass down all of the things I have learned, then what was really the point to ever learning it or experiencing it? And I am not talking about things you can learn from a book, I mean the lessons of life experiences.
Not sure if that is a great reason, or even if it is really the reason. Just my guess from introspection on it. Why is it that I felt now was really the time?
