100% agree, and to add it can be tough sometimes to walk away from a cool project. I had worked on a project building scientific trial software, an app to review 3D lung scans, and an ML model to detect lesions in lung scans. It was really empowering, but after the first scientific trial the customer stopped paying their bills and ended up in back payment of $1M. My boss closed the project which sucked but it ultimately cost the company and people’s jobs. Just not worth interacting with bad people if they stop the agreement. There is most likely more money later but there is also money that is on time with other customers.
