From time to time silence is good you can then listen to your own thoughts and ideas. Some of that stuff you've been learning needs to incubate with a bit of quiet. No need to cut out your audiobooks altogether just give it a break from time to time and notice how it affect you. Perhaps you have a bit more clarity when thinking perhaps not.
A tip for you if you jog and listen with headphone. Lower the volume. Peoples ears are more sensitive during exercise.
