For me it does, but I would rather put it the other way round: when I was in a happy relationship, I was much more productive, single focused and my mind was always sharp and clear. Unfortunately it didn't last. Now I'm back to the ups and downs of shitty single life. For me the big thing was the future security of being in a long term relationship. I'm early 30s and don't want to end up alone. I don't live to work, although I do my work gladly and enjoy it. But I work for a purpose and without a wife and kids, I have no purpose.
