Reality.. a big word

I watched this movie "The Fountain" on this weekend, a great reality of life ,what I grasped is "acceptance". The acceptance of the realities around us ,the acceptance of the very strange things that happen to us, the things that we dont expect at all, the acceptance of the harsh truth that all we are do is actually in vain, the people around us to accept them without thinking to change them. I come to this conclusion that we are part of a bad very bad system but we can just be a better part and if all the parts of a system will be good,the system will be good,so again I am asking to accept it because those who fight against the system they fall back and those who become the better part actually never realize that actually they are changing part of system, they are changing a system.
