The DiSC Profiling is one of the many personality test that's out in the market. One of the more widely used is the Myers-Briggs Personality test, however, it's comprehensiveness tends to turn off people as many are not to excited about filling up a hundred questions. I personally find DiSC to be more practical, and even though it is not as comprehensive as Myers-Briggs, but I find it to be eeriely accurate. Take a online test and find out what your personality is.
To those who have taken the test, why don't post your results in my comments. I've taken the test and scored a high for D and C.
