What shapes my perspective as a knower?

My object was the Mortal Engines by Philip Reeve, after reading it I came up with 2 concepts that still guild me today. The first one is “Life Aren’t Fair”, the portraits the character’s jobs through the social class. This links to my life and makes me think about my future and understand the student’s job which is to have a good GPA and get into book university. Another concept is the base on the perspectives of others, one (I) shouldn’t change because of what others have told me, sometimes the instructions that were given or expectations that were set from outside might affect one’s decision. But everyone is different, you might be the one that is irregular from the majority. So don’t change because others told you to do so.
