But what’s really wonderful is that, sometime between that important day in 1988 and today, my self-image sTOPped being about how I look and began being about how I feel.
sTOP being和began being疑问。
为何要加being？
be about：是动词意义，意为“涉及”。
sTOP 和 begin 后面需要接 doing，包含 being。
sTOP doing ；sTOP being
begin doing ；begin being
假如没 being，你觉得能行吗？
sTOP about ?
begin about ?
再举一个例子：
He is silly. Please sTOP being silly.
没 being，能行吗？ 你能说 STOP silly 吗？
