Gravity and the Rebellious Stone
If there is one thing which an owl has never seen, it's got to be a chunk of rock floating by.
If there is one thing which a rock wants more than anything else, it must be to break the bonds of gravity.
I can't speak for anyone else, but for a large part, I discover what makes me happy by finding out what doesn't, then rejecting it. I'm not really keen on the idea of defining my life by negatives, but it seems to be the way my brain works. One of the most universal human longings has to be to break free from whatever holds us in one place. Whatever that thing is which keeps us from accomplishing our goals.
Paradise then is the lack of unwanted bondage and fear.
Then again, without this adversity, I don't know if I would ever get anything accomplished.
