I really appreciated the insight by Poppy CEO Avni that pursuing your passion might lead you to think you know what you're doing and not be open to feedback, whereas pursuing a combination of curiosity and frustration is much healthier. Food for thought.
An important nuance between the idea that you should be trying to solve a problem vs your problem. Identifying your problem gets you aimed correctly and can be a significant insight, but if you don't accept feedback by dint of determined (unselfish?) curiosity you're likely to overshoot what is actually marketable.
