What is the part that gives you most anxiety when working on your product?

I think it's part of marketing

The most anxiety-inducing part for me is ensuring our product meets user expectations amid tight deadlines. Regular user testing and feedback loops help alleviate this, keeping our focus on solving real problems effectively.

Marketing triggers the procrastinator out of me, every freaking time!

Taking the first step of monetization without loosing loyal users. The challenge of striking the right balance between providing value to users and capturing enough revenue to sustain the business. Only a few products actually did a good job with satisfying users after the monetization. Duolinguo is a good example -- they actually tried to be a language test maker, which benefits both users and higher educational institutions during Covid.

The most anxiety-inducing part for me is the final product launch – it's like waiting for a software update to finish installing, but on a much grander scale! To combat it, I always double-check everything and remind myself that progress comes with a tinge of apprehension.

Product direction, I'd say. It's very difficult to understand what feedback to take and what not to take before a proper product-market fit, but I guess that's the game after all ;)
