關於鉛筆的一則寓言
A Parable of the Pencil
佚名 / Anonymous
The Pencil Maker took the pencil aside， just before putting him into the box.
"There are 5 things you need to know，" he told the pencil， "Before I send you out into the world. Always remember them and never forget， and you will become the best pencil you can be.
"One： You will be able to do many great things， but only if you allow yourself to be held in someone's hand.
"Two： You will experience a painful sharpening from time to time， but you'll need it to become a better pencil.
"Three： You will be able to correct any mistakes you might make.
"Four： The most important part of you will always be what's inside.
"And Five： On every surface you are used on， you must leave your mark. No matter what the condition， you must continue to write."
The pencil understood and promised to remember， and went into the box with purpose in its heart.
Now replacing the place of the pencil with you. Always remember them and never forget， and you will become the best person you can be.
One： You will be able to do many great things， but only if you allow yourself to be held in God's hand. And allow other human beings to access you for the many gifts you possess.
Two： You will experience a painful sharpening from time to time， by going through various problems in life， but you'll need it to become a stronger person.
Three： You will be able to correct any mistakes you might make.
Four： The most important part of you will always be what's on the inside.
And Five： On every surface you walk through， you must leave your mark. No matter what the situation， you must continue to do your duties.
Allow this parable on the pencil to encourage you to know that you are a special person and only you can fulfill the purpose to which you were born to accomplish.
Never allow yourself to get discouraged and think that your life is insignificant and cannot make a change.
鉛筆被放入盒子前，鉛筆製造商把它拿到一旁。
他告訴鉛筆：“在我將你送到世界各地前，你要知道五件事，並時刻銘記在心，永遠不要忘懷。這樣，你才能成為最好的鉛筆。
“第一，你能做出許多偉大的事情。前提是，你必須允許別人用手握住你。
“第二，有時，你會體驗被削尖的痛楚，但這種經曆會讓你變得更優秀。
“第三，你要能改正自己可能犯下的任何錯誤。
“第四，內芯是你身體最重要的部分。
“第五，你必須在被使用的每一個表麵留下痕跡。不論在何種情況下，你都得繼續寫下去。”
鉛筆明白了這些道理，並許諾永遠銘記。然後，它胸懷這個目標進入了盒子。
現在，換位思考一下，把自己假想為鉛筆。永遠記住它們，永不忘卻，這樣你就能成為最出色的人。
第一，你能成就豐功偉業，但你必須允許上帝對你的掌控，並允許他人因覬覦你的天賦而接近你。
第二，你會經曆生活中的各種艱難險阻，不時體驗磨難的痛苦。但是，你需要它們，這樣你才能變得更堅強。
第三，你要能糾正自己可能犯下的任何錯誤。
第四，內在品質是你的最大財富。
第五，你必須在你所有途經之地，留下足跡。不論何種情況，你都必須盡職盡責。

Life Is the Best Beautiful Hope
佚名 / Anonymous
When I was in the 8th grade in Ohio， a girl named Helen in my class had a terrible accident. As she was running to the bus in order not to miss it， she slipped on some ice and fell under the rear wheels of the bus. She survived the accident， but was paralyzed from the waist down. I went to see her， in my 13-year-old mind thinking she wouldn't live normally from then on.
Over the years， I moved and didn't think much about Helen after that. Three years ago， in Florida， my oldest son was hit by a car while riding his bike， causing a terrible brain injury. While I was looking after my son， a lady who said she was the hospital's social worker called. It was a particularly trying day. I burst into tears for no reason and hung up.
A short time later， a beautiful woman， in a wheelchair， rolled into my son's room with a box of tissues. After 16 years， I still recognized Helen. She smiled， handed me the tissues and hugged me. I told her who I was， and after we both got through the shock of that， she began to tell me about her life since we last saw each other. She had married， had children and gotten her degree so that she could smooth the path for those less fortunate than her. She told me that if there was anything she could give me， it would be hope.
Looking at this wonderful， giving person， I felt small. But I also felt the first hope I had felt since learning that my son was hurt. From this person that I thought would have no quality of life， I learned that where there is life， there is hope. My son miraculously recovered and we moved back north， but I owe Helen a debt that I can never repay.
