Jewish sources rarely chase happiness directly. They prescribe the conditions: gratitude, useful work, company, and a limit on wanting.
Pirkei Avot asks who is rich, and answers: the one content with their portion.
התורה העתיקה
“Who is rich? The one who is happy with their portion.”
תרגוםPirkei Avot 4:1 (Mishnah), common English rendering
Standard translations vary between “happy with” and “content with” their portion.

Kohelet — Ecclesiastes — is the most modern-sounding book in the Hebrew Bible. It looks hard at achievement and calls it vapour, then recommends eating your bread with gladness and doing your work.
The result is a strangely durable happiness: unhooked from arrival, built out of ordinary days.
It is unsentimental rather than pessimistic. Having dismantled the illusion that achievement lasts, it returns the reader to bread, work and company as genuine goods.
