You are a WEDF--Wacky Emotional Destructive Follower. This makes you a menace to society, depending on how you channel your energies. You chew your fingers and have an addictive personality. Properly guided, you can be enormously productive--otherwise you run amok, stir up trouble, and generally have a hell of a good time.
To your friends, you are a source of relentless entertainment. You often get into trouble, but you almost always find a way out. You are strangely popular and feed off others' energy. You live hard, seize the day, and although your more sober friends would like to see you settled down, you generally have fewer regrets and better memories than they do. Your tenet is that, at the end of the day, one regrets only what one didn't try. You are right.
You could benefit from outside help in balancing your highs and lows. Or perhaps cutting back on the caffeine.
