1. What made you choose the nature you have right now?
I'm a very cautious person. I think everything I do/say over 5 billion times, and spend forever making sure everything I do is perfect, so nothing can go wrong. (I mean, I spent like 15 minutes typing, editing, and re-editing this post alone.)
2. Are you happy with your current nature?
Based on my previous answer, I think it fits me pretty well.
3. If you could change your nature, what would it be and why?
Nope. I suppose brave, or Timid, would work too, since I'm pretty fearless, and am extremely shy. (Careful, brave, and timid... what a weird combination. lol)
