Learn what magic is, what it can do, what it cannot do, how it works. Learn meditation, visualization, and energy work. Work on learning about protection and shielding, learn how to write and how to cast a spell (if you choose). These will get you started. As you progress you can learn about many other things: herbs, crystals, colors, astrology, tarot, symbols, talismans, charms, demons, angels, spirits, gods, goddesses, religions, ceremonial magic, sympathetic magic, and many more things it takes too long to list.
Keep a journal as you go, many find this useful, it lets you keep track of resources you used, things you learned, questions that come up, dreams, and lets you see later how far you have come.
