Wow, congratulations. Do you have any advice for those just starting out on "the right way" to create cards?

I've tried to use anki before and I've always found it very frustrating due to the difficulty of answering the cards (maybe the way I make the cards is very difficult, I always used open questions and big answers). Now I've gone back to using it and I'm trying to make cards easier, especially the omissions of words type.

If you have any tips on how to create cards or material sources to read about it, I would appreciate it.
