There's a fine line between Elizabeth Holmes, Travis Kalanick, and Steve Jobs.
They all bend the universe to their will. They all inspire people with vividly drawn and compelling visions of the future.
The difference between them, however, is the degree to which they know which rules/constraints to break (many), which to manage through (most), and which to respect (some).
When it comes to managing through constraints, they know how to dig in and pragmatically solve problems instead of constantly reverting back to big-picture nonsense. They don't avoid the details - they crush them.
