For basic descriptions: http://www.2knowmyself.com/a_b_c_d_personality_type Please pick at least one (max 2) major personality types you personally feel fits you best.
Take quiz (will take about 20 minutes or so) http://www.humanmetrics.com/cgi-win/jtypes2.asp to get results. There will be links underneath your result that will help describe and define it. Note, you do not have to answer EVERY question to get a result, HOWEVER, it will be more accurate if you do answer all of them. For a direct description of result, go to: http://www.keirsey.com/4temps/overview_temperaments.asp
Please take quick quiz on http://www.colorcode.com/personality_test/. It is intriguingly accurate for most people. They will not spam you. I have done this myself and purchased the book (I personally didn't find the full results worth it, but the book is if you are interested.) You do not need to include the secondary unless you feel it effects your result. Some people are mainly just one color.
Please pick your top five (5).
