Musk has said that he wants to die on Mars — not as a metaphor but as a statement of the timescale he is working on. Whether you agree with the ambition is beside the point. What the long vision does, functionally, is this: it makes every near-term obstacle proportionally smaller. If your goal is to build a profitable company in three years, a two-year setback is existential. If your goal is to change how humanity exists in the universe, a two-year setback is a data point. The horizon of the vision determines the emotional and strategic weight of every obstacle along the path. For builders anywhere: the length and ambition of your vision is not self-indulgence. It is the frame that determines how you respond to everything that will try to stop you between here and there.
