Big 5 / OCEAN Personality test update

Took another test on a different site and my results are as follows:

What aspects of personality does this tell me about?

There has been much research on how people describe others, and five major dimensions of human personality have been found. They are often referred to as the OCEAN model of personality, because of the acronym from the names of the five dimensions.

Openness to Experience/Intellect
	High scorers tend to be original, creative, curious, complex; Low scorers tend to be conventional, down to earth, narrow interests, uncreative.
		You are relatively open to new experiences.	(Your percentile: 65)
Conscientiousness
	High scorers tend to be reliable, well-organized, self-disciplined, careful; Low scorers tend to be disorganized, undependable, negligent.
		You are well-organized, and are reliable.	(Your percentile: 74)
Extraversion
	High scorers tend to be sociable, friendly, fun loving, talkative; Low scorers tend to be introverted, reserved, inhibited, quiet.
		You probably enjoy spending quiet time alone.	(Your percentile: 12)
Agreeableness
	High scorers tend to be good natured, sympathetic, forgiving, courteous; Low scorers tend to be critical, rude, harsh, callous.
		You find it easy to express irritation with others.	(Your percentile: 22)
Neuroticism
	High scorers tend to be nervous, high-strung, insecure, worrying; Low scorers tend to be calm, relaxed, secure, hardy.
		You tend to become anxious or nervous.	(Your percentile: 66)

What do the scores tell me?
In order to provide you with a meaningful comparison, the scores you received have been converted to "percentile scores." This means that your personality score can be directly compared to another group of people who have also taken this personality test.The percentile scores show you where you score on the five personality dimensions relative to the comparison sample of other people who have taken this test on-line. In other words, your percentile scores indicate the percentage of people who score less than you on each dimension. For example, your Extraversion percentile score is 12, which means that about 12 percent of the people in our comparison sample are less extraverted than you -- in other words, you are rather introverted. Keep in mind that these percentile scores are relative to our particular sample of people. Thus, your percentile scores may differ if you were compared to another sample (e.g., elderly British people).

I'm a O65-C74-E12-A22-N66 Big Five

My thoughts:

Seems pretty accurate. I would say I am original, creative, curious, complex as I'm also an INTJ on the MBTI and an artist, so not totally sure I agree with the score on that? The fact that I am not perhaps as 'open' to trying new experiences is due to the more powerful neurotic trait? Same goes for why I'm 'introverted' and why I'm 'conscientious'- I do a good job because if not I worry I'll get sacked or moaned at etc.

The "Disagreeable" factor is interesting.

I've often said if I were to ever date a girl, she would HAVE TO either share the same values or be very adaptable.
The fact the test proves I'm quite critical of differences by being a disagreeable personality says a lot and explains this opinion. Perhaps as well, the fact I am disagreeable makes it difficult to accept other's opinions, other ways of doing things, and thus I have a much harder time in trying to achieve my goals of transforming my life? I don't want to make excuses or use it as a reason to give up, but it does explain a few things.

I wonder if one can change such personality types and to what degree?
