That depends on what you think magick is.
Magick isn't what you see on TV. There isn't a short phrase that you say and have something happen immediately afterwards. People who practice magick aren't those fancy wizards you see in movies. Magick isn't an "Abra Kadabra Alakazam!" type of thing.
Magick does consist of willpower, energy, desire, and concentration. There are different types of magick, though, such as candle magick, sigils, voodoo, etc., each being a different method of practice.
I have read your bio, you said you put a curse on someone and made her fat. Since you claimed that you did this, why ask for proof?
I don't know what to say about your desperation for proof. You should learn more about magick and try to learn from your own experience.
