How? Well, that's easy. Just go the PhilosophicalPersonality website (http://www.philosophicalpersonality.com/), and take a free, entirely anonymous personality test, while answering a few questions. It's fun and takes only 5 minutes.
Also, if you want to help us, please, send the link to the PhilosophicalPersonality website to your friends and tell them to send it to their friends!
In addition, you'll learn about yourself! You'll find out whether you are extrovert, open to experience, and so on.
