stubborn

A stubborn person doesn't give up easily, even when others think they should.

When people call someone stubborn, they usually mean that this person is not willing to change their mind or compromise. They might be convinced that their way of doing things is best and are resistant to suggestions from others. You can hear this in everyday conversations: "Stop being so stubborn!" or "He's just too stubborn to listen." In most cases, the word "stubborn" implies a kind of determination or persistence that might come across as obstinate.
