My childhood and adolescence were a joyous outpouring of energy, an endless pursuit for expression, skill, and experience.        was only a background to the great delight of lessons in music, dance, and dramatics.
Then one night at a high school dance, a remark, not intended for my       , injured my youthful happiness: “That girl, what a pity she is blind.” Blind! A(n)        word that implied everything dark, blank and helpless.       I turned and called out, “Please don’t feel sorry for me, I’m having lots of fun.”      the fun was not to last.
In college years, I began to struggle with the problem of earning a living. Part-time teaching of piano and occasional giving concerts proved only        sources of economic support. In terms of time and effort involved, the financial return was       . Self-doubt and dark moods sparked within me.        to my misery was the repeated experience of knowing my sisters and friends dating excitedly. How        I was to my piano,        I could dissolve my frustration, accompanied by Chopin, Brahms, and Beethoven.
Then one day, I met a girl, an army nurse, whose faith was to change my life. As our acquaintance        into friendship, she sensed my       . She said, “Stop knocking on closed doors. I know your opportunity will come. You’re trying too hard. Why don’t you relax? And have you ever tried       ?” The idea was strange to me. I had always believed that if you wanted        , you had to go and get it for yourself. Yet, my sincerity and hard work had yielded poor returns, so I was       to try anything else. Self-consciously, I performed the daily practice of prayer. I said, “God, show me the        for which You sent me to this world.
In the years to follow, the answers began to arrive, satisfying        my most optimistic expectation. One of the answers was Enchanted Hills, where my        friend and I had the privilege of seeing blind children come alive in God’s out-of-doors.        are the sources of pleasure and comfort I have found in friendship, and most important of all, I        closer to God and, through Him, to immortality (永生).
