How do you deal with the supposed four ultimate existential concerns? Namely,
Death - How do you reconcile man's short lifespan with the desire for achievement, the finite with an innate hope for the infinite?
Meaninglessness - Assuming there seems to be a lack of inherent objective meaning in the universe, and that is truly a cold and unforgiving place, how do you find the motivation to excel and maintain a sense of compassion?
Freedom - If choices are unlimited, how do you avoid become hopelessly lost?
Existential Isolation - If ultimately, no one can truly know you or understand you, how do you overcome this essential feeling of loneliness?
