You never need someone to mentor you, you can simply do all that on your own. Since, most of these mentors here, and everywhere else most of them have no clue of what they are even doing. It is best that you take it upon you, to research/study, and practice magick.
Having a base foundation of understanding what magick really is will help you add the building blocks to more advanced information you will learn in the future. Understanding the spells and all that I would say ties into a basic understanding of what magick is.
Remember to take subjects that interest you and learn about them, research so you can find these topics.
And also remember to do what you think is best for you.
The whole coven thing, you don't even have to join a coven. You can be solitary if you chose to be.
