Well it's true. If you're all about career, success and big goals then it's better to live alone. A lot of great minds and great people in history lived in complete celibacy all their lives. Not to mention that in the past kings and aristocracy only married to get offspring and increase their land and power, they didn't care about love and all that cheesy stuff.
It's a lifestyle that some people prefer but I guess it's hard to understand for many people in this degenerate society where most people don't have any higher ambitions than getting laid.
