成熟就是在有尊嚴的範圍內，思考並將你的感覺化為語言與行為的能力。你在挫折之中展現出的心靈精神，是你成熟度的衡量依據。Maturity is the ability to think, speak and act your feelings within the bounds of dignity. The measure of your maturity is how spiritual you become during the midst of your frustrations.

Maturity is the ability to think, speak and act your feelings within the bounds of dignity. The measure of your maturity is how spiritual you become during the midst of your frustrations.
