In 1997, the balance sheet at Apple Computer was a study in corporate fragmentation. The company was bleeding $1.04 billion in annual losses, and its product catalog had ballooned to 350 separate items, including a bewildering array of Macintosh variants that even the sales staff struggled to differentiate. When Steve Jobs returned to the campus in Cupertino that year, he didn't look for new markets to conquer. Instead, he took a marker to a whiteboard, drew a simple two-by-two grid—'Consumer,' 'Pro,' 'Desktop,' and 'Portable'—and effectively fired 340 products. By 1998, a billion-dollar loss had turned into a $309 million profit.

This was not a triumph of creativity, but a triumph of subtraction. The tension at the heart of most commercial failures is not a lack of opportunity, but an inability to manage the weight of it. Most executives view a 'yes' as an additive gain—a new revenue stream, a fresh demographic, or a strategic partnership. In reality, every 'yes' is a silent 'no' to something else. It is a withdrawal from a finite bank of cognitive and capital reserves.
