There seems to be nothing wrong with this sentence, but sometimes I can’t even believe it! I am so confused, can I believe in myself? For example, if someone is taken to a pyramid scheme, can this person follow his own heart and go astray? Never trust anyone around you, only you can trust yourself! You can see this sentence said by bad guys in many TV dramas. Those people are hurt by others (accidental injury) or deceived by life, and fall (devil path) and become bad people, evil people. In the end, they will say such words with emotion! If life deceives you, don't be discouraged. There are still many good people in this world! If there were too many bad people, the world would be in chaos!
