What is the most frustrating aspect of Product Management?

Been in the PM role for quite some time. There are a few things that I love, but that’s probably only 20% of my time. 50% is normal but the rest 30% is quite frustrating. In different roles (seniority wise) and different companies, some of these issues overlap. I want to hear from fellow PMs on what are their feelings. What’s the most frustrating part of PM role?

Probably I am simply looking for a rant echo chamber 🫂
