I recommend reading the author's blogs & listening to their podcasts. The goal is to have their core ideas drilled into your head, and sometimes that takes time. Having a cadence of a weekly blog post does that much better I find. Maybe don't try to read the whole book in one week, but rather space out each chapter over a long period of time so that the message "sticks" with you.
