決心善待年幼者、同情年長者、支持奮鬥者、包容弱者及犯錯者，你一生遲早也都會歷經這些過程。Resolve to be tender with the young, compassionate with the aged, sympathetic with the striving, and tolerant with the weak and the wrong. Sometime in your life you will have been all of these.

Resolve to be tender with the young, compassionate with the aged, sympathetic with the striving, and tolerant with the weak and the wrong. Sometime in your life you will have been all of these.
