My Temperament Test result

I did a personality test, if you are interested you can read the below. I think it is very accurate, in the same time I realize how much things I should change myself. In doing the test, I believe many people they do personality just for fun, but never take serious about themselves. Many people think that I wish to be like that person because he/she is good at .... Then, what happen, few days later they are the same. I think personality is a habit and they can be developed. 

The Melancholic / Phlegmatic The melancholic-phlegmatic is tidier, more procedural and less flexible than the phlegmatic-melancholic. He may be slower to take on new projects, as the melancholic fear of new situations and tendency to perfectionism takes over. The double-dose of introversion, along with the melancholic tendency to negativity, makes it difficult for him to give compliments and make upbeat small talk. It also causes him to instinctively say "no" when he first hears a request. Others may perceive this as "snobbishness." Unless the melancholic-phlegmatic is very comfortable, and is surrounded by understanding long-time friends, he may find himself somewhat isolated and alone, unable to warm up in a social gathering. He is less critical and less grudge-bearing than a pure melancholic or a melancholic-choleric. However, the tendency of the melancholic to dwell on things for a long time in their mind, combined with the sensitivity of the phlegmatic toward interpersonal relationships, can result in long-lasting hurts, an erosion of self-confidence and self-esteem, and even depression. Extremely sensitive and possessing a longing for the ideal (melancholic), they are also highly attentive to what others need or desire, through their phlegmatic aspect. This makes them more than usually susceptible to anxiety and a negative self-image This temperament combination is highly driven to succeed—not for success' sake alone, but because their melancholic nature is drawn to high ideals, and their phlegmatic side will have a strong desire to please. Thus, they are capable of long-range planning, organization, and attention to detail that makes them excellent and conscientious scholars. They are capable of pursuing highly idealistic goals, usually with long-term academic requirements, such as attaining their doctorate. They value their friendships, but can spend many hours alone reading or studying. They may have a tendency to hypochondria or to genuine physical weaknesses, as well as a tendency to timidity and anxiety, especially about new activities or ventures. One melancholic-phlegmatic we know is highly organized, critical, slow, and dogmatically unforgiving, yet reveals her phlegmatic aspect in her intense discomfort with confrontation (unless she is very at ease among the warring members) and in her strong relationships with her friends. You wouldn't guess that she is so devoted to her friends, however, because true to her melancholic nature she rarely initiates contact with them – they always have to call her first. A tendency to avoid the stresses of social interaction by spending overmuch time alone—whether in scholarly pursuits or reading for relaxation—is something that melancholic-phlegmatics need to watch out for. If your temperament is melancholic-phlegmatic, for a better understanding of your temperament it is recommended that you read the full descriptions of the melancholic and phlegmatic.
