Gratitude is the feeling or quality of being grateful. And I think only a gratitude person or individual could truely be great. No matter in what area. Science~Technology-Economy~Politics, Relationships or even Arts etc. Eventually, WE are A WHOLE.
Newton once said,
That is some kinds of gratitude.
I has been over 3 years, However, I can clearly remember as if it just happened yesterday.
"Can gratitude bring us health and happiness?" That definitely true.
