    When US teenager Jake Olson isn't playing football or golf for his high school, he's often offering inspiration(灵感)through his new book about his own life.

    These activities might be too much for the average 16-year-old to deal with, but Jake is blind. When people ask him how he can possibly play golf without being able to see the ball, he says he is thankful for his father's guidance.

It seems apparent that his early experience playing sports as a person with sight and muscle(肌肉) memory— repeating behaviors over and over until they become second nature — have also enabled Jake to hit the ball quite well.

    Jake was born with a rare kind of eye cancer that took away the vision from his left eye when he was a baby and eventually his right eye, in 2009, when he was 12 years old. Rather than letting the disease hold him back, Jake used his loss of sight and his faith as sources of motivation(动力).“If I was going to sit on the couch all day, feeling sorry for myself, I wasn't going to do anything. I decided that I was going to go out and persevere (坚持不懈).” he said.

    It was with that mind-set that the student from Orange Lutheran High School in California was able to write his first book, Open Your Eyes: 10 Uncommon Lessons to Discover a Happier Life. “It's about opening the readers' eyes to their true talent in life and making sure that they use all the abilities that they have,” Jake said.

    Jake's father, Brian Olson, said the family is impressed with what he has done with his life, including showing people that they can get through hardships. “Your darkest hour can soon become your brightest, and with every setback, there's a setup,” Jake said. “In every one of us, there's more potential than we can ever imagine, and it really is a choice.”

游褒禅山记

（宋）王安石

    褒禅山亦谓之华山，唐浮图慧褒始舍于其址，而卒葬之；以故其后名之曰“褒禅”。今所谓慧空禅院者，褒之庐冢也。距其院东五里，所谓华山洞者，以其乃华山之阳名之也。距洞百余步，有碑仆道，其文漫灭，独其为文犹可识曰“花山”。今言“华”如“华实”之“华”者，盖音谬也。

    其下平旷，有泉侧出，而记游者甚众，所谓前洞也。由山以上五六里，有穴窈然，入之甚寒，问其深，则其好游者不能穷也，谓之后洞。余与四人拥火以入，入之愈深，其进愈难，而其见愈奇。有怠而欲出者，曰：“不出，火且尽。”遂与之俱出。盖余所至，比好游者尚不能十一，然视其左右，来而记之者已少。盖其又深，则其至又加少矣。方是时，余之力尚足以入，火尚足以明也。既其出，则或咎其欲出者，而余亦悔其随之，而不得极夫游之乐也。

    于是余有叹焉。古人之观于天地、山川、草木、虫鱼、鸟兽，往往有得，以其求思之深而无不在也。夫夷以近，则游者众；险以远，则至者少。而世之奇伟、瑰怪，非常之观，常在于险远，而人之所罕至焉，故非有志者不能至也。有志矣，不随以止也，然力不足者，亦不能至也。有志与力，而又不随以怠，至于幽暗昏惑而无物以相之，亦不能至也。然力足以至焉，于人为可讥，而在己为有悔；尽吾志也而不能至者，可以无悔矣，其孰能讥之乎？此余之所得也！

    余于仆碑，又以悲夫古书之不存，后世之谬其传而莫能名者，何可胜道也哉！此所以学者不可以不深思而慎取之也。
