Reading the sources
I’ve made a habit the last few years to read the original sources.
The book. The earnings calls themselves.
So much fidelity is lost in the summaries and rewrites. If you read the original, you understand exactly what they were trying to outline. You pick up on the excitement that made other people write up or summarise this work.
I.e. a podcast episode you enjoyed is based on one or a couple of books, grab those books and read them, the fidelity of reading the source materials will yield so much more.
Those are the things that tickle the brain.
