What do you think of this advice a friend gave me about dating?

She says just because somebody is attractive, does not mean they will make you happy, and that she knew people who married very attractive people who were miserable.

My dad married an extremely attractive woman, and my dad had been miserable every day of his married life.

My uncle married an average looking woman, and he has had a much happier marriage than my dad.

I know, because I lived with my uncle and aunt and cousin every summer in America, when I was not doing my 8-10 month school year, here in Canada.

Once I became an adult, our paths diverged and I stopped spending my summers with my cousin in America, since I did not have American citizenship, and would not have been allowed to work a job in America.
