Info dump alert, Anki is a deep deep rabbit hole. These resources have helped me immensely. I didn't have any specific hurdles in mind - I had many "eureka" moments, but they were highly personal, only applicable to my situation. In the words of Michael Nielsen "Anki use is best thought of as a virtuoso skill, to be developed", so don't get discouraged by this big list, take one step at a time. If I had to give only one recommendation then the top link would be it.
