Vision / Mission / Strategy
I always mix up vision, mission, and strategy until I saw the mountain analogy.
Mission: Climbing the mountain, step by step.
Strategy: The route we take from base camp to the top.
Vision: The view from the summit, the ultimate destination.
The mission drives your action, the strategy ensures you get there safely and the vision inspires your direction.
Great leaders inspire their teams to yearn for the "Vision".
