I have a fear, that I can do less than I think that I can. I know, that doesn't make much sense. But it's like this: I always want to be able to think that I can do more. I don't want to study non-stop because then, if I fail, I will know that I cannot do any better than that, and that scares me.
Or I don't want to run as fast as I possibly can, because then I will know I am not capable of running any faster than that.
I want to always know that I can do more, that I am capable of more. This is a very real fear, as real as being afraid of the dark (which I am not, by the way) or of snakes (I can of am). A fear of finding your limits.
Maybe we all live in this idealistic thinking, that we really are, or could be better than anyone else. Maybe, deep down, we are afraid of finding out that is simply not true.
Which is the real limit? We would like to think that it's the sky.
