Is it worth it to play heads up LIMIT with someone who you are not MUCH better than?

I'm having trouble taking the 5/10 cent part out of picture.

One of the recurring themes in reading/writing about poker is understanding motivation. If you are playing .5/.10 limit heads up, it can't be just for the money. Youl could likely work a minimum wage job and earn more an hour.

So it must be something else - the fun of the competition, to improve, an unmonitored broadband connection at the office, etc.

Is it worth it just for the money? No, of course not. But you might have other reasons.
