I’ve started my notebook. Perhaps I should similarly streamline other areas of my life.
One thing it has shown me is that my Japanese approach is too fiddly. It’s difficult to keep track of 4 resources (audio and printed text in both languages). To have to prepare a different pair of files every 4 or 5 minutes is simply too complex.
All I really need is the Japanese to listen to and read, and with the English to refer to when necessary. It may be best to do that with physical books instead of a split screen. Plus the audio.
