I Admire Wit and Intelligence

"A person cannot be intelligent if they can't take responsibility for their own life. You are not in a bad mood because another person is annoying you, it is your bad mood, and YOU are allowing that person to get on your nerves." i think you are wrong, emotional intelligence and logical intelligence do not go hand in hand. You can be in control of your emotions and be an idiot at the same time.
Actually most of what you say only ties to emotional intelligence and not intellect.
"They listen to what people have to say, and can accept that other people have opinions that may be different from theirs. " This i agree with.
"An intelligent person asks questions when they aren't sure, they never assume or jump to hasty conclusions." an experienced person does that, an intelligent person makes hasty mistakes like everyone else and learns trough experience.

"
An intelligent person WANTS to learn, anything and everything, and they always welcome different perspectives. " not true, an intelligent person can be extremely focused and goal oriented, intelligence doesn't necesarily mean eclectic.

"
They are never afraid to try something new, or to be wrong about something they thought they knew." an intelligent person is still a person and fear is a human trait, many brilliant minds held on to wrong ideas.

Being an intelligent person, your definition is pretty close. The only thing I would change is the mood thing. An intelligent person knows how to redirect the conversation or avoid the situation that would influence their mood. One area you are missing is sharing. Intelligent people pay attention to detail and love to share their knowledge but it isn’t always appreciated.

Excellent definition

I think you have great perspective.

Well put.
