"A person who doesn't know what the universe is, doesn't know where they are. A person who doesn't know their purpose in life doesn't know who they are or what the universe is. A person who doesn't know any one of these things doesn't know why they are here. So what to make of people who seek or avoid the praise of those who have no knowledge of where or who they are?"
— Marcus Aurelius, Meditations
This is a really deep topic and is a really tough one to compare to trading!
Trading wise we know who we are, what we are doing, what we are trying to achieve and why we are doing it too of course.
This however runs much deeper than that, so I will leave it for us all to think about.
