Use adaptive to describe people who are flexible — they don't lose their cool when plans change quickly and they are always willing to learn new ways to do things. Being adaptive helps you sail along in today's ever-changing world.
What do chameleons and your grandparents who only started using computers a few years ago have in common? They are adaptive. Just as chameleons change color to match their surroundings — green when sitting on leaves, brown when climbing the tree's trunk — your grandparents learned the skills to keep up with the world around them. The opposite of adaptive is stubborn. People, lizards, or anything that refuses to change are stubborn. To welcome change is to be adaptive.
