Welcome @katie23! I’m Siofra_Strega a moderator here in the forum from Cape Cod.
I also agree with this! I had started in my teens & well, life happened & just recently came back to my practice fully in 2020 & found Spells8 that July. Since then… I haven’t been happier & have learned so much more than I dreamed I would. There have even been times within those 2+ years that I have had to completely restart, refigure, step back for a variety of reasons. As with the anything, life tends to wax & wane & go through cycles. Perfectly fine though! We will always be here for you!
As @marsha had mentioned the courses… I also agree that those are a great start. There is a lot of great information, even if you already have worked with or “know” the information, it’s a great refresher & oodles of topics to choose from!
@Amethyst & @marsha are also correct, everyone here is very helpful & friendly… so if you have any questions feel free to ask & someone will be along to get you pointed in the right direction. Also feel free to jump in on any open topic or start your own if you have something to share with us! We love to learn things!
We do have a Whole Tarot Course as well as 
Tarot Poems by The Gifted and Talented Amethyst that go through each of the cards if you need a refresher with the tarot. Also on the Daily Devotional there is a virtual Major Arcana draw for you to try each day.
I look forward to getting to know you better & learn with you too!
