In my experience women have much better emotional control. I've seen so many women clearly express no interest in university classes but still be able to put the work in to pass. For men, I've seen that if they have no interest in something, they have a hard time getting themselves to see something through. On the other hand, I've also seen a small group of men become obsessive over something and pretty much neglect everything in pursuit of this obsession which I'm sure in the long term leads some of these men to be at the top of their fields.
