An underlying trait I've found throughout my entire life is that I like to give. The thing I've found most gratifying is helping or giving to those close to me. In a relationship this translates to wanting to provide for or make someone else very happy. Not to say gold diggers apply, but I simply find it makes me happy to make others happy.
As for hobbies and interests keeping fit/healthy is definitely up there for me. I love the outdoors, through hiking, biking, swimming, camping, or a motorcycle. I also used to do ballroom and latin dance for about 5-6 years. I taught myself how to play piano and guitar; don't claim to be good at either, but can get by. I like cooking all different types of cuisine.
