The type of personality I'm attracted to is someone who is funny, whether it be witty, goofy or dry, as long as they do not take themselves or life so seriously. Intelligence is important, someone with good common sense, who is thoughtful and empathetic. A person who is comfortable with who they are, self aware, and confident. Be passionate about something, be it a hobby or a job. Someone who has goals in life, even if they are small, and that they work towards them. Being kind, defending those that are weaker, and being tough when the situation calls for it is very attractive. I could probably write more but those are what I could think of off the top of my head.
E: Oh, and don't try to change me. Love me for who I am and I'll do the same.
