Fantastic piece Jessica. Balanced, pragmatic, humble, yet pointed and encapsulating. This paragraph hits it off the ballpark: "Happiness is a balancing act. Too much striving will likely leave you lonely and miserable. Not enough will leave you regretful. And much depends on how you mark your progress. Are you judging by internal measures like mastery and impact or external ones like glory and money?"

Part of the "internal measures" I think is the word "calm" in the great man's 17 word note. For without calmness and inner peace, happiness will remain out of reach, no matter how enormous the outward success is.
