She didn't complain what she doesn’t have; she changed her attitude towards life and became successful.

Hawking was being detained in a wheelchair for 40 years; the disease has made his body completely deformed. Even so, Hawking has not given up, he was tenaciously survived. Despite his debilitating illness, he has done ground-breaking work in physics and cosmology and his several books strive to make science accessible to everyone. He didn't have the ability to change his adversity, but he kept a good attitude and he didn't complain; he became success.
