Some positive things I'd describe myself as: optimistic, friendly, empathetic, self-sufficient, open-minded, tolerant and creative. I'm looking for someone who I can spend some time with when I'm not working my weird hours (I work 6pm-2am most days, and my days off are Sunday/Monday).
If you want some pseudo-scientific data to look at, here are some personality profiles on me:
Big Five/OCEAN: High on Openness, extraversion and agreeableness, very low on conscientiousness and neuroticism.
Current favorite quotation:
"It is the mark of an educated mind to be able to entertain a thought without accepting it."
