improvisable 

Creation of an appropriate substitute

When people believe that their ability is improvable as opposed to improvisable they tend to set their goals and handle failure constructively in order to facilitate motivation.

improvable 

A place or thing which can be improved, a person who is capable of improving themselves or is willing to listen to someone who wants to show them how to improve.

Eddie is not improvable, he doesn't even answer his Father's telephone calls or emails because he does not want to listen to his Father's advice. It seems he thinks he knows better.
