Taylor Swift spent 6 months singing her 40-song setlist on a treadmill every day. Before rehearsals even started.

Beyonce spent 8 months preparing a 2-hour Coachella set. Some days lasted 11 hours. Over 200 performers and hand-picked every detail. Steve Jobs started rehearsing his keynotes a full month before launch. To deliver a presentation that looked completely off the cuff. Last month, I made a client rehearse. They didn't think they needed to. Halfway through, they understood. Effortless requires a lot of effort.
