Even in the horrors of a concentration camp, humans retain the ultimate freedom to choose their response to suffering, proving that a life driven by purpose can endure almost any hardship.
The fundamental driving force of human behavior is the search for a unique and specific life purpose, rather than the pursuit of momentary happiness or dominance.
The last true human freedom is the ability to choose one's attitude and internal response regardless of external, unchangeable circumstances.
Meaning can be reliably discovered through engaging in creative work, experiencing profound love for another person, or adopting a courageous stance in the face of unavoidable suffering.
