Don't ever let anyone tell you that fate determines everything; you are your own person. You make your own choices. Both the past and the future are constructs established by the human mind to prevent the re-occurrence of mistakes and prepare for the tragedies to come. We create our own present. 

And that's why, when you go to jail for transporting your friend's packages across the nation, the contents of which have escaped your thoughts, ignorance of the law does not work as an excuse.
