He who has a 'why' to live for, can bear with almost any 'how'

Our reading
An editorial interpretation.
A reason for living is presented as a source of endurance through difficult circumstances. The contrast separates purpose from the conditions under which life must be lived. Almost keeps the claim from being absolute, suggesting powerful support without promising that meaning makes every hardship bearable.
