The term “hacking” has a bad name. It comes out of coding and refers to someone trying to gain control over a computer system, typically for nefarious purposes. The word then morphed a bit, becoming pop culture shorthand for a “quick fix” or a “shortcut.” — None of those definitions apply here. First, the system we’re trying to gain control over is our own neurobiology. Second, when it comes to sustained peak performance, there are no shortcuts.
