Contrary to his image as a master planner, Napoleon claimed he was "ruled by circumstances." He avoided rigid, long-term plans, opting instead for flexible projects. His genius was not in controlling events, but in bending his policies to align with their unforeseen shape as they unfolded.

To avoid accumulating sunk costs on doomed projects, solve the most difficult, uncertain part first (the "monkey"). Avoid easy tasks (building "pedestals") that create a false sense of progress. This framework, from Google's Astro Teller, forces an early confrontation with a project's core viability.

Thinking in decades is a trait of the ultra-wealthy. To make this practical, create a 25-year vision and then build a "work backwards plan." Sequentially map out milestones from 25 years to 10 years, three years, one year, and finally to the current quarter. This deconstructs a massive goal into achievable steps.

A naive 10-year plan just schedules current low-priority items for the distant future. A better approach is to define a massive 10-year ambition and work backward to identify the foundational "arcs" you must invest in today to make it possible.

True business agility requires constantly syncing nested plans—tactical, operational, and strategic. It also involves managing efforts across three time horizons: the 'now, next, and beyond.' This military-inspired framework ensures immediate actions align with long-term vision amidst constant change.

Napoleon used a two-stage process: deliberate, pessimistic planning where every risk is exaggerated, followed by unwavering, rapid execution once a decision is made. This framework separates analysis from action, eliminating hesitation when it's most fatal.

Instead of creating an intermediate, 'half-step' product, commit to the harder but optimal solution if a plausible path exists. This avoids the wasted effort and sunk cost fallacy of a circuitous development path, even though it requires more upfront investment and conviction.

A key lesson from the visionary-but-failed company General Magic is to articulate a grand vision, but then immediately focus on a much earlier step that could be a viable business or product in its own right. This grounds the team, forces practical execution, and prevents the "all vision, no product" failure mode.

To balance short-term needs and long-term goals, create accountable teams that own a component of the overall vision. These teams must control the entire product lifecycle—from discovery to implementation—so they can make intelligent near-term trade-offs without losing sight of the strategic goal.
