I think a big problem in current society is the fact that a lot of Humans are overly distracted by sentiment. We let friends, pets, family, and sentiment get in the way of our future.
If you're a good business person, than I'd say it's fair that life's goal is to succeed. Life has no other purpose. Socializing for the sake of socializing is a time waster that often creates friendships that produce chemicals in the mind which encourage the individual to continue this non-business-conductive behavior-- all the while, the individual is distracted from looking toward the future, and focusing on goals.
For those of us who place high value in socializing, and indeed that is most of Humanity, of course our lives will revolve around getting married, and doing things that is expected of us socially such as buying a house, and making bills.
On the other hand, if you look out at this world and think to yourself.. The only way life will have a point is if I give it one, and I choose to dedicate my life to "Insert business idea that will help the world". Once one has made the choice... to walk this path. The path of business, the path of good choices over bad choices, the path of tactfulness, reliability, competence, efficiency, then I think the Human will begin to have success in their business venture.
I know that.. as Humans, we are social creatures, but simply enjoying the company of someone isn't enough. It's important to surround ourselves with people with whom we can mutually benefit.
