Is Marriage Really a Barrier to Success?

     The writer of a post i read somewhere about successful women opined that to get to a certain level of career success as a woman, you need not be married. I.E, you need not even have a relationship with the opposite sex that could lead to anything. A list of some renowned successful ladies were given as proof. I do not quite agree with this and i'm thinking maybe this is obtainable only in third world countries (or not). I want  to know what you think. Is marriage really a barrier for you that's a career person or an aspiring career person? would you rather be married than to be globally recognized based on your success? Or do thing both can be carried? Let me know what you think.
