You cannot control the circumstances of your life. You are in an environment that you didn't choose, working with values that you didn't choose, trying to choose to do something that matters to you. Your sphere of influence is exceedingly limited, and if you just borrow meaning from the world around you, you risk being at the whim of this environment. A sense of purpose that transcends your job description, that reaches beyond even the importance of your own livelihood can help your mental health and definition of success far more than anything else. What is it that you want your existence in this world to say? Building upon everything we've learned about critical thinking, lateral thinking, and emotional intelligence, this is the lecture to pay attention to.
