"Behind every successful guy, there is a powerful woman," says an old adage that appears to be more accurate than not. Because of the facts we have on persons in the public eye, it is easy to test this adage by looking at the lives of renowned people throughout history. It turns out that it is quite true: almost all famous men had a wife or partner who played an important role in their success. For example, Albert Einstein was married with two children when he came up with his theory of relativity. Winston Churchill was born into poverty and inherited a family estate at the age of 24. Thomas Edison was fired from his job as a telegrapher before he became one of the most important inventors in history. Bill Gates dropped out of college to start Microsoft. And the list goes on and on. None of these men would have been able to achieve so much if it weren't for the power of women. Their energy and motivation helped them realize their dreams and become great leaders. There are also many famous men who had no family at all or only a mother. Such people include Steve Jobs, Andy Warhol, and Charlie Manson. The fact is, if a man doesn't make any friends after puberty, he is probably suffering from some kind of depression. So I think we can assume that having friends is very important for a happy life.
