Found via Seethruskin. This sounds right to me; Maybe not quite as sunny, but definitely the part about wasting my time on stuff that seems futile:

you are lightcyan #E0FFFF

Your dominant hues are green and blue. You're smart and you know it, and want to use your power to help people and relate to others. Even though you tend to battle with yourself, you solve other people's conflicts well. Your saturation level is very low - you have better things to do than jump headfirst into every little project. You make sure your actions are going to really accomplish something before you start because you hate wasting energy making everyone else think you're working. Your outlook on life is very bright. You are sunny and optimistic about life and others find it very encouraging, but remember to tone it down if you sense irritation.
