Smart, goal-oriented, has a sense of humor (or at least laughs at my jokes), has hobbies, likes to keep fit and encourages me to do so, supportive, kind, a great cook, not a picky eater, adventurous, extroverted (or at least is willing to help me get out of my shell), interested in traveling and other cultures, doesn't necessarily hate math... oh, and I'm a sucker for women with brown hair. Like, in a big way. Also, not religious.
