Well sense you say your a witch, I would suggest reading about witchcraft. Then reading about the difference between witchcraft and Wicca. Those two are usually confused to being the same. Even though they are different.
Spells should be used when you know more about magic(k) and how to use energy and wield it. The more you read about magic(k) you will learn something new.
Like there is no black or white just intent.
Magic(k) is merly energy and only energy.
