As one cannot always rely completely on supernatural forces, Macbeth murdered the king to make sure his ambitions came true.
This play written by Shakespeare was first performed in 1606.
Many years and manslaughter later one can say that the same forces, supernatural or only human, have been going on working in this line.
There will always be witches and you can be sure that they're busy whispering:
"By the pricking of my thumbs,
Something wicked this way comes."

So be aware of those witches when they whisper in your ear that one day you will be recognized as a great artist.
