I'm a beginner, any tips?

I want to start practicing some kind of witchcraft, I have no idea what I'm doing and most info I find online is very confusing and is using terms I don't understand (what do you mean I'm a Capricorn north node what does that mean 😭). I do some tarot for fun, I say affirmations to my crystals before putting them under my pillow and sometimes I carve sigils on candles. I really like herbs and growing stuff, I collect crystals, I love burning candles. School is really stressing me out right now, exams and other stuff like that, so I can't give it all of my time. Any recommendations where I should start?
