Dedication, usually people's thinking cognition is that I am for everyone, everyone is for me, and I am for everyone's purpose, actually for myself. Although this kind of cognition has dedication, its essence is for itself. When the immediate interests or immediate interests are greater than the limits set by themselves, they will still give up their principles and do more for themselves. The dedication is not complete. A person who can treat others as his relatives is undoubtedly very dedicated, but in essence, such dedication has only changed from a small self to a small one, and it is still selfish without leaving the category of "I". Dedication is also incomplete.
