I think I will start listening to podcasts on cassette. I think it's a good filter. If it's not worth the extra time to transfer then perhaps it's not worth it to me to listen to.
I realized after this trip I'm listening to a lot of low quality media and it's just too easy for this media to filter in my head.
Perhaps also nice would be to summarize a bunch of media into 90 minute audio that I could then record once a week.
I'm not sure if this will be a permanent switch, but I think I will try this experiment.
Also, I'm probably not listening to enough music as well :)
