The 4th Factor
Man thinks that he can achieve anything. He believes that there is nothing in this world he can’t do.
But, he doesn’t realize that his efforts and equipment are not enough to decide the results of his actions. Sometimes, he does his best but things don’t work out the way he wants.
He then realizes the importance of the 4th Factor, a factor that makes the possible, possible and without its consent even the possible becomes impossible.
