Dear John,

    My name is Amber and I want to share my story with you because what you've shared about life and positive energy has changed my life. This past year has been one of the hardest for me. I felt I was stuck in a position that had nothing to do with what I wanted to do with my life. In January, after two years of being together, my boyfriend left me.

    I read your blog every morning as I drink my coffee at work, but it wasn't until this March that I told myself "no more negativity" as you taught readers in your blog.

    Since then I've got into new habits at work to keep my energy positive. When people walk in the front door, I'm the first face they see, so I smile big when I say "good morning" to them, especially on Mondays. Instead of waiting for someone to ask me for help, I offer it with an open mind. The CEO noticed my change and offered me the executive assistant position that I wanted.

    One of the biggest things I've taken to heart from your blog is changing my opinions on my job. Yes, it was not an important position, but when I was passionate （热情的） about it, I could make my life fulfilling.

    All in all, I have to thank you somehow for having the passion to help others because it truly is inspiring to me. So thank you so much, John. My life has changed because your words pointed me in the right direction, Take care!

                                                 Sincerely ,

                                                     Amber

    【甲】陈康肃公善射，当世无双，公亦以此自矜。尝射于家圃，有卖油翁释担而立，睨之久而不去。见其发矢十中八九，但微颔之。

    康肃问曰：“汝亦知射乎？吾射不亦精乎？”翁曰：“无他，但手熟尔。”康肃忿然曰：“尔安敢轻吾射！”翁曰：“以我酌油知之。”乃取一葫芦置于地，以钱覆其口，徐以杓酌油沥之，自钱孔入，而钱不湿。因曰：“我亦无他，惟手熟尔。”康肃笑而遣之。

    【乙】楚有养由基者①，善射，去柳叶者百步而射之，百发百中。左右皆曰“善”。有一人过②曰：“善射，可教射也矣③。”养由基曰：“人皆曰善，子乃曰可教射，子何不代我射之也？”客曰：“我不能教子支左屈右④。夫射柳叶者，百发百中，而不已善息⑤，少⑥时气衰力倦，弓拨矢钩⑦，一发不中，前功尽矣。”
