a will to live
A will to live is when you’re so stubborn you refuse to die even if you’re being yelled at by a loud, angry teacher.
I had a will to live when I stayed in class even after the teacher threatened to throw my notebook out the window.
My cousin has a will to live because she still goes to school even though she failed all her tests.
My neighbor has a will to live because he still talks to me even though I told him to stop.
