Less sleep. Less free time. And definitely less "us" time with the missus.
I find myself worrying about the child more than I would like to admit. I'm always thinking about "what if" and go take a bunch of precautions.
Furthermore, as a parent, I found myself taking financial decisions more seriously and become involved in more investment ventures and smart savings because I hope my son will benefit from what we built for him later on.
smart savings seems a good idea in order to keep everything under control in the future. thanks for the answer
