请问有没有人知道下面这段话是出自哪里的?哪本书还是电影?
Whether you die at a young age or when you are older is less important than whether you have fully lived the years you have had.One person may live more in eighteen years than another does in eighty.By living,we do not mean frantically accumulating a range and quantity of experience valued in fantasy by others.Rather,we mean living each day as if it is the only one you have.We mean finding a sense of peace and strength to deal with life’s disappointments and pain while always striving to discover vehicles to make more accessible,increase and sustain the joys and delights of life.
