If you don't already, practice consuming zero intellectual content now and then, to give your brain time to synthesize. Let yourself be bored. Instead of swimming in the (highly engaging) sea of ideas, drift in intellectual deprivation awhile, at least breathing, perhaps doing something tangential like walking or physical labor (without music or other distractions from the important work of giving yourself mental space). Also, accept that you'll never learn it all, and that it's okay to keep learning despite that--it's the journey, and you're writing your book, which has a final chapter. Good luck!
