I like to do personality tests — it is a way to review and learn about yourself. Once I found a very simple assessment on personality type. To me, its design was quite smiliar to Carl Jung's model. (I have seen one with over 100 questions before.) And the fact is, it does relate to Jung: the inventor Catherine Briggs and her daughter Isabel Myers developed this Myers-Briggs Type Indicator (MBTI) based on Jung's works. It measures four bipolar factors: Introversion versus Extroversion, Thinking versus feeling, Intuition versus Sensing, and Judging versus Perceiving.
You could assess your type with only four questions in PersonalityType.com (the most convenient test) and then see the simple descriptions on your kind. If you want to explore a little bit more, I recommend you to visit Wikipedia for theoretical details and Keirsey.com to look at David Keirsey's further development on the test. It is quite referable, as I belong to the type of INTP in MBTI and Architect Rationalist under Keirsey Temperament Sorter. If you have time, do it — try to find out own personality and learn more about yourself.
