Mutual desire sparks a relationship. Mutual respect sustains a relationship. We need both.
I think that it can be dangerous to become overidentified with one's work. I love my work and I'm passionate about what I do, but relationships and sharing time and interests have more to do with happiness than professional accomplishment or the material trappings of success. I love travel, particularly big cities, New York, DC, London, but smaller out of the way places like Santa Fe can charm me too. I've spent a lot of my free time in the past few years working to develop a private foundation, and that's been tremendous fun, in terms of what I do locally, as well as seeing the world.
A healthy relationship depends on mutuality. I would like to find someone who shares my beliefs in that area. As far as other things, like music, politics, etc, I'm open to difference; in many ways, I am drawn to difference.
