Make your Anki cards one at a time. Quality over quantity.
It's very easy to add 10,000 words and translations/definitions into Anki using import tools and scripts. If this works for you, great! But I often see people do this and then a month later feel totally crushed by hundreds of reviews information completely out of context.
Instead, try studying and only make a card when you have an "Aha!" moment. "Oh, that's what that word means" or "Ahh, I see how the past tense works". Ideally, cards should feel a little bit too easy when you make them. It should feel like you're never going to forget the new word that came up 20 times in this chapter of your textbook. Of course, after a week or so your memory will be a bit more fuzzy and the Anki card will be a helpful reminder to prevent forgetting.
A bonus of this method is that now doing Anki reviews is like remembering all your best hits and moments you were really clever. It's the complete opposite of a grind.
