There is no single path to insane greatness.
Picasso and Gogh are both artistic geniuses, but they pursued very different routines to stay prolific. Success is more a deliberate practice of what works than a serendipitous streak of luck or privilege.
The path to greatness is paved with tiny consistent rituals.
I recommended Daily Routines of Nikola Tesla, Mozart, Hemingway, Woody Allen, Maya Angelo, van Gogh, Stephen King… on Medium.routines
