I chose Nord firstly because I thought I was going to make a character similar to me, but after failing I got back to the Race tab, searched through the abilities to see which race is best to choose, and after not being able to decide I just got back to my Nord lady, tweaked her a bit and that's it.
Also, after thinking, I liked my choice even more since I decided to be a melee fighter. (currently I mix one-handed weapons with spells but at the end of the day I go back to my dear warhammer)
