If you were to die now, at this moment, what would you think of as the best thing you've ever done in your life?
That was the first thing that came to my mind after reading the question. I was (and still am ^^) alive and I experienced many things, some of them good, and some of them bad and really awful. 'Life' was the first thing I thought about and I'll just stick to that.
If I had a chance to change something in my life, I wouldn't change anything. I'm happy and proud of who I am. And that I'm still alive.
Where?: still here
