I use ChatGPT for almost everything. It has become my daily assistant as a product manager, helping me complete tasks faster and think more clearly.
I also configure it to challenge my thinking and find alternative perspectives. Because of that, it works like a sparring partner during brainstorming sessions. It questions my assumptions, provides different angles, and often supports its reasoning with references from journals, books, or established theories.
This makes it incredibly useful not only for execution, but also for improving the quality of my decisions and ideas.
