The weakness of human is greedy. When seeing the things others have, wish ourselves could also have. When seeing delicious food, would like to bite a bit more, When hearing the chance to earn money, thinking ourselves could also earn the same.
It is right to be ambitious as well as improving, but must consider the ability and must have the consiousness of danger.
World economy seems more and more not optimistic. With the hope that myself don’t be greedy with anything.
