As I write this, I'm sitting in a cafe in Paris overlooking the Luxembourg Garden, just off of Rue Saint-Jacques. Rue Saint-Jacques is likely the oldest road in Paris, and it has a rich literary history. Victor Hugo lived a few blocks from where I'm sitting. Gertrude Stein drank coffee and F. Scott Fitzgerald socialized within a stone's throw. Hemingway wandered up and down the sidewalks, his books percolating in his mind, wine no doubt percolating in his blood. I came to France to take a break from everything. No social media, no email, no social commitments, no set plans . . . except one project. The month had been set aside to review all of the lessons I'd learned from nearly 200 world-class performers I'd interviewed on The Tim Ferriss Show, which recently passed 100,000,000 downloads. The guests included chess prodigies, movie stars, four-star generals, pro athletes, and hedge fund managers. It was a motley crew. More than a handful of them had since become collaborators in business and creative projects, spanning from investments to indie film. As a result, I'd absorbed a lot of their wisdom outside of our recordings, whether over workouts, wine-infused jam sessions, text message exchanges, dinners, or late-night phone calls. In every case, I'd gotten to know them well beyond the superficial headlines in the media. My life had already improved in every area as a result of the lessons I could remember. But that was the tip of the iceberg. The majority of the gems were still lodged in thousands of pages of transcripts and hand-scribbled notes. More than anything, I longed for the chance to distill everything into a playbook. So, I'd set aside an entire month for review (and, if I'm being honest, pain au chocolat), to put together the ultimate CliffsNotes for myself. It would be the notebook to end all notebooks. Something that could help me in minutes but be read for a lifetime.
