Burnout&#x27;s likely whenever you work really hard on a product that nobody uses, regardless of what your role at the company was.  It sucks to sacrifice hard for something that doesn&#x27;t pan out.<p>The solution to that isn&#x27;t to only work on the stuff that pleases you, though.  It&#x27;s to only work for companies that have traction or at least demonstrated consumer demand.  It&#x27;s the founders&#x27; job to validate that there&#x27;s a reason for the company to exist; make sure they&#x27;ve actually done their job before you entrust them with yours.
