Went and took the personality test at thespark.com and this is what I learned on 20 minutes of work time:
( Dominant Introverted Abstract Thinker )
You are an EXPERIMENTER (DIAT). Although you're slightly shy (admit it!), you love control. When a problem comes in your way, you stomp on it swiftly and decisively. You are bothered easily by failure in others and failure in yourself. You don't like people that you don't think are intelligent. Rather than arguing with them, however, you would just as soon ignore them altogether.
In relationships, you have a strong heart. And because you're introverted, people take you as someone they can trust. But the fact is that in addition to solving problems, you like to create them. So there's a decent chance that you'll cheat on a loved one. If you do, you'll likely get away with it.
You're a good person at heart, but then again, who isn't?
Go in Peace
