See the main entry: Fortitude
Fortitude is sustained courage — the capacity to endure difficulty over time without losing heart. Where Courage is about the moment, fortitude is about the long game. It’s showing up on day 100 with the same commitment you had on day 1.
In the context of radical thinking and building new systems: every worthwhile change requires fortitude. The status quo has inertia. Institutions resist change. People resist change. Building something genuinely new means enduring skepticism, failure, loneliness, and doubt — for years.
Every great movement, company, and creative work was built by people with fortitude. Not genius. Not luck. Fortitude.
