Hi Miranda! Welcome to the Forum!!
My advice would be to take some time to practice meditating first. Learning to silence your mind and focus your energy is extremely important to the work you’ll do. I personally suggest you practice on visualization as well because it can be a very powerful thing.
I suggest you follow this audio guided meditation course
Ultimately, your intention is what matters. If you don’t have everything you need for a spell, you can always look for or write a different spell, but if you have to, you can always substitute.
It is completely possible to practice witchcraft without any tools, but your tools and ingredients carry deep symbolism and meaning so they will be your “training wheels” as a beginner. As you progress in your path, symbolism will come down to its personal meaning to you.
There are many types of witches and witchcraft, don’t feel like you need to label yourself right away.
Practice candle safety!
Go through this list of lessons and you’ll find most beginner things are covered there!
As @christine4 mentioned, books will be your best friends ! I personally also recommend “Drawing Down the Moon” by Margot Adler
