The way I see it:

If I could summarize in a very concrete and sublime way, why I have decided to do what I am doing professionally, that will be David Foster Wallace‘s 2005 commencement speech to the graduating class at Kenyon College. (The speech was made into a thin book titled: This Is Water: Some Thoughts, Some Thoughts, Delivered on a Significant Occasion, about Living a Compassionate Life).

"Learning how to think really means learning how to exercise some control over how and what you think. It means being conscious and aware enough to choose what you pay attention to and to choose how you construct meaning from experience. Because if you cannot exercise this kind of choice in adult life, you will be totally hosed. Think of the old cliché about “the mind being an excellent servant but a terrible master.”

No presentation needed. Just click play and immerse yourself into it. I am sorry millennials and generations Z, this is not a fancy edited video, it is a still image. Suggestion: close your eyes, and just follow his voice. Recommendation, play as many times as necessary.
