David,

As a rule of thumb I think that a well-balanced person cultivates both and can use them liberally in all circumstances.

There's a famous incident in psychology (which may or may not have happened) where an interviewer asked Sigmund Freud what mental health looked like. Freud pondered that for a moment and responded "To love and to work."

Meaning that, in his estimation, optimal health was the ability to connect with others and put good things into the world. And in practice they tie in with each other; most people's work is enriched by the ability to connect and form meaningful relationships with others, and most people's meaningful relationships are made richer when the person is a responsible and reliable person who can accomplish meaningful work under pressure, using nothing but their own volition and skill.

Beyond that, I would agree that yes, some situations will call for more of one than the other. But it is hard to picture one where they do not blend. Even in the purest forms of love there's work to be done, and even in the purest forms of work there is joy in sharing it with others.
