The ancient Norse were known for celebrating courage and resilience, but their wisdom also extended to everyday struggles such as anxiety and overthinking. One of the most enduring sayings from the Old Norse tradition comes from the Hávamál ("The Sayings of the High One"), a collection of wisdom attributed to the Norse god Odin.
The proverb reads: "The unwise man stays awake all night worrying; when morning comes, he is weary, and his troubles remain."
