One thing that i’ve been lately doing is listening to Tolle then right after write down a bullet point of the Gem that I really liked. Think of this gem as the phrase of the day. Tolle drops a fuck ton of nuggets on the audio book (practicing the power of now).
The goal is to not memorize the entire audiobook verbatim, it’s to have a deeper understanding of it. So that at some point you’ll actually internalize it. Usually from what I’ve experienced is to internalize something is to act on it.
BTW: I usually write down the bullet point (quote) on one of my whiteboard’s but now i’m thinking of transferring those to a journal/notebook, then once a week reflect on these briefly.
