I believe in balance in life so I'm looking for someone who can relax and dream with me from time-to-time but at the same time can keep focus on the important things and is practical and organized. If you can't ever turn off your Blackberry at least for a few hours (at least symbolically) or on the inverse you can't understand that sometimes you need to use one, you may not find me very compatible.
The willingness or interest to share activities is important to me. We don't have to have the same personalities or nature but should be good compliments to one another. I don't fret the small stuff as we all have faults and issues. I like to look at the core of a persons being and their principles before I worry about how they dress or what movies they prefer.
Oh, and you have to be ready to nurture the relationship. While I do believe in "love at first sight" (hey, I'm a romantic), I don't believe in lasting love based just on that. Love is like a flower. You at least have to be willing to learn to be a good gardener.
