I have some nice flash card decks on anki but have failed to make it a habit to look at them. Did you have any ideas on how to make it a habit to do these reviews? For me some of these flash card decks are kind of heavy (e.g. Deriving some equations) and I think my brain just does not always want to get into it.
In my experience it does not work for "heavy" questions.
I successfully developed a habit for "quick" questions, where you know the answer instantly once you learned it. Examples: Capital of Malaysia? "Car" in chinese? Phone number of Mom? Images work well, like "what country does this map show?"
For heavy questions the repetition feels like too much work. Deriving equations is probably heavy. Another example would be: List all states of the US.
Deriving equations is not fun for my mind, because it takes seconds or minutes of concentration. For the quick questions, I receive success dopamin before I even notice that it is work. Fun. It becomes a game and I sometimes did a few cards on my smartphone while waiting, for example.
One strategy is to split heavy questions into many quick ones. Unfortunately, I don't know what to do if splitting does not work.
