It is a material reflection for me, There is an old Chinese proverb says:
"to see, I know" ... "to hear, I understand" ... to undergo, I see "..
Due to the always grateful will make us happy ..
It is a short answer to that is a manifestation of man is a sense of gratitude. Gratitude is a quality of the heart that matters. With grateful we will always overcome with a sense of peace, calm, and happy. Instead, feeling grateful will always weigh on us. We will always feel less and unhappy.
There are two things that often make us thankful.
First, we often focus on what we want, not on what we have.
The second thing that often makes us grateful for is the tendency to compare ourselves with others.
Indeed, O all, gratitude is indeed very unusual and very, very beautiful and happy hearts!
