It was a hard choice but I chose confidence first, after being torn between that, sense of humor and intelligence. Those are equally important to me, but my reasoning is that if someone isn't confident, I won't really look twice at you no matter how funny or smart you are. And even if I notice those two traits first, if I find out someone is too insecure it's a turn off.
A mix of many personality traits are important to me.
Honesty is valued and respected.
Confidence is admirable and attractive.
The ability to be "sweet" or kind can brighten your day.
A sense of humor is important. Laughter is important in life, being able to laugh at ones self is a nice trait. It shows you have some humility.
Intelligence is important. The ability to carry on a conversation. Being able to attain thoughts and share thoughts and views. Of course their are different types of intelligence. Most importantly I like when a person has wisdom, with that you have the recollection, foresight and ability to logically see the world for what it is.
