First you should research the basics of magick, what is needed what it is about and found out if it is right or you. You need to develop yourself before you get into magick, like meditating, chakra work, visualisation work. Then learn moon phasses and such.
A great place to start would be the internet there are literally thousands of free guided meditations to start off on. Once you feel comfortable and can feel your energy and meditate and visualise goals clearly then you can start with magick.
A good beginners book would be solitary witch by silver ravenwolf she has put lots and lots of info in this book and despite what people think of her other books this book is a great achievement you will learn eveything you need to practice sympathetic magick, once you have done this I would begin looking into high magick but only when you are advanced and only if it is right for you.
Startin points would be getting the book reading it decide wether you want to be a witch and then look at the tools section and get wat you think necessary and a witch can never have too many candles or herbs which inturn all have different meanings, also incense and such.
