There&#x27;s actually a commonly repeated lesson there (although I forget the popular source) -- You should have passion for the <i>problem</i>, not passion for <i>your</i> solution to it. If you&#x27;re passionate about the problem, and it&#x27;s a real one (it&#x27;s unlikely you can be passionate about an imaginary one), there&#x27;s no such thing as too much passion. If a solution you worked on for hundreds of hours isn&#x27;t the right one to solve the problem you&#x27;re passionate about, that passion will overcome your attachment to the solution and you&#x27;ll be willing to pivot.<p>Have passion for the problem, and even if other people have attempted to solve it, your passion will help you solve it better than them even.
