The document provides advice and lessons the author wishes they had known when they were 22 years old. Some of the key lessons include: to trust one's own intuition rather than always believing what others say, as some people will lie; that having a job does not define one's life and career paths can take many forms; and that one should be well-informed by widely researching topics from different sources and perspectives rather than being unduly influenced by others. The author also wishes they had known that not everyone follows principles of compassion and ethics and that what is considered "right" or "wrong" may be open to interpretation.
