لا تنغرس شجرةٌ وتشتدّ ما لم تعصف بها ريحٌ كثيرة؛ فهزّها هو ما يشدّ قبضتها ويُرسّخ جذورها، أمّا الأشجار الهشّة فهي تلك التي نمت في وادٍ مشمس.

“No tree becomes rooted and sturdy unless many a wind assails it. For by its very tossing it tightens its grip and plants its roots more securely; the fragile trees are those that have grown in a sunny valley.”Seneca the Younger
