On a more serious note, two principles most dear to me are reason and compassion.
I'm generally introverted and mild-mannered. But I have a very positive outlook on life (without being overbearingly upbeat). I can be perceived as quite, but I think small and frivolous talk is overrated and I typically choose my words carefully and tactfully. However, I never shy away from an intriguing conversation and know when to let loose and have a little fun.
