I think I would rate the most important trait, for me, as being ethic. It's something I admire and make a lot of effort to be.I also enjoy politeness, inquisitiveness, calmness, expressiveness, empathy and comprehensiveness.Taking our society as a context, I do like rebellious and non-conformist people.
I would say positive thinking ALL the time however - it would mean i'd be very biased. SO in saying that, One trait i would like to have is being more open minded. Instead of always focusing on the negatives in life, i would love to start experiencing both worlds.
