Are You More Productive When You Are Single?

I was speaking to one of my cousins the other night and I pointed out to her that she seem to be more productive careerwise when she's not in a serious relationship, i.e. shacking up, engaged, or married as opposed to just screwing from time to time. She had never really thought of it that way but she sayed I was right. Without the daily drama, affection responsibilities, LOL, etc., she do get a lot more done.

If you look back throughout your life, do you feel that you are more productive when you are single or in a committed relationship? I read a book awhile back about women who do not succeed in their careers because they put too much of their time and energy into relationships. I wonder if that is why a lot of women are waiting until later to get married and if there is a direct correlation to women owning more businesses and making more money than ever.

One of the case studies in the book was about a woman who had been held back because of a man but once she decided to redirect her energy, she went from being a waitress to realizing her dream of owning several restaurants. What are your thoughts?
