Want your project/organisation to be viable long-term? It needs a plan for the immediate phase, and it needs to dream about subsequent phases.
Many startups get this wrong, in both directions.
Either *everything* is a dream, so nothing is ever concretely decided or acted on (and the constraints are not apprehended and processed).
Or the *only* thing that matters is the current plan, which causes tunnel vision.
Success requires planning and dreaming working in harmony.
