“Don't speak negatively about yourself, even as a joke. Your body doesn't know the difference. Words are energy and they cast spells, that's why it's called spelling. Change the way you speak about yourself, and you can change your life.” - Bruce Lee

Without the word, would we have science? Could we explore space? Words are magic and we cast spells when we speak or write, but to see it as such, we have to recognise that existence is magical in itself.

What do you do when you speak or think negatively of someone?

Do you not "cast a curse"?
