Hello, my little wraith! You can turn almost anything into a spell. As seraphickalmagick said (and I absolutely love this line): “The key to doing magic is deciding that you’re doing magic.” That link also has a few simple everyday spells that are great for new witches.
Personally, I feel these are some great places to start: casting a circle (this was my first thing I did as a witch), consecrating any magickal tools you might have, and calling on the elements to protect you during your craft. These are all things you’ll probably need to do either frequently or eventually, and they aren’t too complex.
Keep in mind—and this is solely my belief—the most powerful spells/rituals come from the heart. In other words, write your own spells and stage your own rituals. If you don’t know where to start and need inspiration, read some spells/rituals that other witches have written/performed, and then tailor it to your energy, purpose, and beliefs. Follow what your witch’s intuition tells you, and believe in yourself.
And if you feel like you “mess up” or “do it wrong,” don’t worry. We all feel like we have no idea what we’re doing at first. But eventually it will be second nature. :)
