People are always greedy.

People are always greedy, so they will keep making progress, and therefore they will be more intense when they fail.

People are always greedy, so you and I always sometimes ignore the original purpose in order to go further, thus getting lost and uncomfortable.

People are always greedy, so we are all competing for better resources. The terrible thing is that we don't cherish what we have.

Life is like a dream, like a day for decades. We are more and more greedy because of the thoughts in our hearts. When we can't go back to the past, we know the original beauty, so there is a "if".

Please cherish what you have, because people are always fragile and easy to lose.
