For young people starting out having goals is very important to keep one moving in the right direction. Goals are easiest to achieve when you understand your strengths and weaknesses. Personality impacts everything in our lives from the way we understand information to how we set upon achieving those goals. Gaining a sense of self understanding also helps you to work using your strengths and using others to hedge your weaknesses.
For example, I have had many goals and for the most part I accomplished most of them. Now I have bigger goals about giving back and doing some good things. Often when we start out we have very little insight into ourselves but as we age we gain more insight through necessity, feedback and reflection (Or at least we should). Sometimes the environment reflects accurately and many times it doesn't.
A few words of caution. Never assume that all personality and psychological tests are 100% accurate and are the definitive assessment of you. They are based on constructs and in turn reliability happens over time. Any test you find anywhere could be a good one or a bad one and that is based in validity and repeatability. Few tests can sum up a person from a few questions. Multiple tests from different vantage points might be more useful. (Keep that in mind while hiring employees that personality-psychological tests should be seen as secondary and supportive.)
Almost all tests have some errors. More unique people may register differently simply by being out of the bell curve and not having the same underlining thought processes that went into the test validation process. In today's world, creative unique people have benefits for innovation and alternative solutions. i.e. cognitive diversity. There is no such thing as good or bad in one's personality, only variance of life. Popular Personality Tests — How to Gain Self-Understanding and Set Your Goals

I'm a Loyal Friend.....
"Others see you as sensible, cautious, careful & practical. They see you as clever, gifted, or talented, but modest. Not a person who makes friends too quickly or easily, but someone who's extremely loyal to friends you do make and who expects the same loyalty in return. Those who really get to know you realize it takes a lot to shake your trust in your friends, but equally that it takes you a long time to get over if that trust is ever broken."
