if all you have is a hammer, everything looks like a nail

used to convey that if one's only tool is one narrow skill or way of thinking, one will tend to try to use that single approach for everything, even when it is not the most appropriate solution
The origin of the proverb "if all you have is a hammer, everything looks like a nail" is attributed to psychologist Abraham Maslow in his 1966 book 'The Psychology of Science.' It suggests that if a person relies solely on one tool or approach, they will tend to apply it to every problem, even when it is not the most appropriate solution. The proverb emphasizes the importance of having a diverse set of skills and perspectives to address various challenges effectively.
