In the last few months, I have leaned more towards audio based learning but I have realized that personally audio is great for shorter content (less than 1 hr). After 1 hour, I get distracted because I feel like I could listen and do something else. Then when I pause and think what I got out of the last few mins of hearing, I realize I wasn't paying real attention. I also tried listening for 1 hour, taking a break and listening for another hour. I am unable to recollect what I listened last time while I have no problem recollecting material I read. For example, I am "reading" two books simultaneously now - one from kindle and another via audible. If you asked me what I learnt from the audible book,I would struggle to summarize. I am part of a book club and one of the women I see there has great notes on every book she has read. She was telling us how audiobooks aren't any good because to truly understand content, you need to pause, assimilate what you just read and process it (she writes it down). Audiobooks do not give that break. I usually ask Alexa to pause and resume but it plain sucks to do that.
