This is an opinion – so don’t get excited.
Begin with a blank journal and a deck. That’s it. What do the cards mean to you?
Does not matter what they meant to somebody in 1856, or 1953, what matters is what they mean to you now.
Posting for other peoples opinions does not make sense until you figure out what it all means to you.
As you learn the cards, you’ll have questions about what various symbols mean. That’s what you should follow up on. Like when you ask yourself about the guys shoes on the 7 of Wands (WCS), or the triangle within the square on Temperance. Search out the meanings of those symbols, and not what they mean on Tarot, but what does the triangle within the square mean outside of Tarot? Why did they incorporate it?
Allow your own learning to lead you to further learning.
Or, you can take the ‘Be a Fortune Teller for fun and Prophet’ course and become a keyword parrot.
Edited to add: But them I'm a reader. Further, I'm a reader who reads for strangers. If you want accurate history, go to the books. If you want inacurate history, hit the books. There is some real trash out there bound between covers. As the man said, "Choose wisely."
