I might be the Bizarro version of youI'm 35, I was never very interested in family, marriage, children, relationships, but being a millennial, from my background, a family would have essentially just insured poverty, assuming I married in my early 20's, from someone from a similar background.
I'm 35, and always had a goal of family, marriage, children. So much so I got married in my early twenties to a girl with the same background. Child came shortly thereafter.
Ironically, assuming the responsibility of keeping a roof over my new family's head and putting food on the table forced me to focus solely on their well being while grinding harder than I ever would've if it was just me. As a result, I've been very fortunate financially. I ain't rich by any means, but we are very comfortable.
