So first, I recommend writing out a few things and keeping them for yourself. Kinda like a wedding album or a baby book of your magical doings and ideas.
Second don’t go wild trying to buy all the things! What tool or item most intrigues and attracts you, maybe get or make one of those and really get to know it. You can do so much with just a wand, or just a mortar and pestle. Maybe you just have to grow mugwort, go ahead and get a plant or some seeds and learn everything you can about that. Or maybe tarot just calls to you, get a deck and work with it. In some cases a whole magical practice can be focused around one tool or a small set of herbs (I could do almost anything I need to with just half a dozen).
Third, if you got a how to book, read it and try it! Hey magic is in the doing, set forth some of your will into manifestation. Don’t let anything hold you back from what you want to do (as long as its not heinously immoral! If you could get put in prison for doing it mundanely, *probably* shouldn’t do it magically as a beginner).
Fourth, don’t act like a know it all! This is not the time to start teaching others, or writing public blog posts explaining all about magic to everyone. These things are best for your personal journal. And unlike many areas of spirituality, most people don’t already have a reasonable baseline understanding of what magic is. So if someone asks you about your spirituality or religion and you start off with one of them magical fields as your answer, be the first to admit you don’t know everything about it and cannot be expected to explain it all. I mean if someone says they just decided to be Christian, people don’t sit and demand they explain all about Jesus to them and the finer details of theology, they say, oh good for you where do you go to church? (that’s an easy one to answer!)
Finally, find a few people who you can ask questions of and befriend them. I like to base my choice of mentors off a few things. I like them to compliment my weaknesses—I am a tad too nice, so I pick someone gruffer and tougher than me, I like a challenge so I look for someone who will inspire me to push myself. And I also look for someone who has their life together and is magically potent. I don’t want someone who is fawning all over me while secretly figuring out how to use me. I am not looking for a friend or someone who agrees with me on everything and I don’t want a mentor who is looking for that in me as a student too. I am a very different kind of mentor than what I am looking for, which is funny, but tis true. See you have to make your own list, many of the folks I mentor were looking for someone just like me, and nothing like my mentors are/have been.
Thank you for the great ask and best wishes on your path!
