        I remember as a small child at gatherings (聚会) with family or friends, someone would ask: "What are you

going to be when you grow up?"

        At first I said I wanted to be a cowboy or some super hero. Later it was a fireman, artist, architect

(建筑师)… As I grew older my dreams of the future changed. When at last I was in college, I was asked: "What

will you major (主修) in?" By then I had my heart set on becoming a computer programmer. So I studied and

prepared for that life. I was designing software full-time for much of my life.

        I am content (满意的) that could realize my dream. However, for many, there is a "thief" who goes around

stealing our dreams.

        We find ourselves close to reaching our goal. Then we hear this small voice inside our heads saying: "You'll

never make it." "You can't possibly do this." "Very few have ever done this successfully." On and on, the voice

predicts (预言) some kind of failure.

        Don't listen to that voice. There are no overnight (突如其来的) successes, but with perseverance

(坚定不移). It will come. Imagine yourself in the life you dream of living. Then in your heart, believe it will

happen for you, as it has for others. Then work, work, and work! You get the picture.

        Be true to your dream, and don't let anyone steal it from you — especially yourself. You can do anything

your heart desires, so don't give up or give in.
