SaaS founders, what has been your #1 struggle?

No judgment, no pitch just real talk and i wanna hear
I’m genuinely curious about whats keeping you up at night as a SaaS founder?

Is your landing page traffic ghosting you? Stuck in MVP development hell? Struggling to validate your idea?
Burned by bad freelancers/agencies?

Vent here. No sugarcoating. Bonus points if you share a story.
