Ask HN: How to balance incremental SaaS building with a big long-term vision?

Hello

I’m building a SaaS product and struggling with a common tension: having a clear long-term vision while only being able to make progress in small, incremental steps.

How do you decide what to build this week without losing sight of where the product should be in a few years? What mental frameworks or heuristics help you avoid both over-architecting early and drifting without direction?

Interested in practical approaches and lessons learned.

Thanks!
