Seek sound judgment from a happy heart;
the first capital of well-being is having enough.
A weak arm cannot deliver a strong sword stroke;
in the same way, no right decision comes from a broken heart.
Explanation: The 'sword from a weak arm' is a metaphor: just as a feeble arm cannot strike hard, a troubled heart cannot make good decisions.

تدبیر صواب از دل خوش باید جست
سرمایهٔ عافیت کفافست نخست
شمشیر قوی نیاید از بازوی سست
یعنی ز دل شکسته تدبیر درست
