What helped you stop underpricing your product when starting out completely solo?

When you're the only person working on a project, imposter syndrome hits hard when setting up a pricing page. Every time I get close to setting a fair rate, I talk myself down to a fraction of that cost just to avoid getting rejected by early users.

Everyone preaches "charge more," but without an established brand or team behind you, it feels like you'll just scare away every visitor.

If you struggled with this early on, what specific mindset shift or experiment helped you find a pricing level that actually felt fair?
