You are your best teacher. Remember that while some people can help guide you on their path, that guidance is limited. Witchcraft is more of an internal process of figuring out who you are inside, what you can do, and what you need to improve on. Only you can figure this out as you are the only person who has access to your spiritual self. Do not expect others to teach you, either. Thank the people who give you some guidance as they do not have to do so.
Don’t be afraid to try things out without permission/asking. There is no need to ask someone else if you can do a spell or other witchcraft related activity. I’ve seen many people ask others if they can substitute an item for another item, if it would be okay to perform a spell in another way, and many more questions. Just do it. There is no need to ask, there is no need to get permission. This is your spell, your work, do what you want with it. No one else can promise you the results if you perform it a certain way or if you do it another way, so just try it out and see what happens. Do the spell as you want to and see what happens.
