Don’t do evil because it’s small, and don’t do good because it’s small.

During the Three Kingdoms period, Liu Bei once said: "Do not do evil because it is small, and do not do good because it is small." Don't do bad things when you think they are small, and don't do good things when you think they are small. This sentence talks about the principles of life. Evil, even small evils, cannot be done; good, even small good deeds must be done.
