The power of positivity. I can shrug off negative things, or twist the perspective and see it in a different light. Somehow that annoys some people. I just don't see the point in negativity.
Luck of heroes. Not specifically in minor things, but in big things like finding an internship, or passing a year of school, I somehow manage to pull through without any effort at all. Where most people would worry to death about what to do next, I can usually say that it'll be al right.
Cat's grace. I only once have been injured seriously, after a falling from five meters on my neck when I was about six I nearly broke my it that time, but I 'just' sprained it. Besides that, I always landed on my feet without a real scratch. Also, I can move through crowds with uncanny agility and speed, without appearing to make an effort at all.
Strong mind. I can negate pain, just by thinking about it. It doesn't work with headaches unfortunately, but I can move my headache around in my head, which is kind off funny.
