How do you find the time/energy to get the example sentence on the back of each card? Do you have a process/method to make it easier? When I encounter new words in real life, it tends to be all at once (i.e. watching a show while making dinner). I scribble the word quickly on a nearby notepad and don't have time to look at it again until I'm bulk-uploading new words later. It bothers me that I'm maybe not getting the full benefit of Anki, because I'm missing the context and/or example sentences. I would love to hear ideas about how to resolve that timing issue. I seem to retain more from those 20k word decks you mentioned than my personal decks, likely because they come with example sentences and context that my personal decks are missing.
