# Definiteness doesn’t have anything to do with vision Shamans and psychotics have visions. Visions say “we should vaguely go towards those mountains.” Visions are generally not falsifiable. I’ve never heard of a startup that says “welp, looks like you’ve failed to meet your vision.” You also can’t argue with a vision beyond “I don’t like that vision.” Instead [[Definiteness means that you have a long-term plan]] towards a goal. [[Notes from CS183: Startups]] does not mention the word vision once in the whole discussion of Determinism and Optimism.  ### Related [[A definite worldview means you believe the universe is deterministic]] <!-- #evergreen --> [Web URL for this note](http://notes.benjaminreinhardt.com/Definiteness+doesn’t+have+anything+to+do+with+vision) [Comment on this note](http://via.hypothes.is/http://notes.benjaminreinhardt.com/Definiteness+doesn’t+have+anything+to+do+with+vision)
