内心宁静，精神充实，简朴的生活也能过得很快乐；内心浮躁，精神贫乏，即使有了富裕的生活，还要拼命追逐外物。所以，关键是取决于你怎么过，而不在于你有什么。
When our mind is peaceful and our spirit is rich, our simple way of life can make us very happy; When our mind is restless and our spirit is poor, we still chase after outer materials desperately, even if we are wealthy. So the key to a happy life lies not in what you possess, but in how you live your inner life.
