It was one of the happiest times of my life. I was 29 and had just received my bachelor’s degree, graduating with   36   despite working two jobs and being a wife and mother. My parents and five-year-old son were among the   37   when I walked onto the stage at Ashland University to get my diploma. I was so excited and proud to be starting a teaching career and contributing more to my family’s happiness.

But when I got home that evening, there was a note from my husband,   38  , “I have come to get my clothes and won’t be back.” We’d been having trouble,   39   that note still came as a shock. He had emptied our bank account. We were horribly in debt. I had quit my previous jobs in the hope of finding a teaching position.   40 , I was eight months pregnant.

The reality was so merciless that I was embarrassed,   41  , and angry and felt I had failed. But I had my son, and I was about to   42   a new life into the world. So   43  my deep sadness, I had to go on. The next morning, I woke up, put my feet on the floor, took a deep breath, prepared breakfast, and basically did everything I always did. I used my routine to keep myself moving.

And in the seven years since, I’ve continued moving forward. I got a job as a kindergarten teacher, earned a master’s degree in education, and watched my babies grow to 12 and   44  . I certainly have never   45   to put them through this, but in retrospect (回首往事), I’m glad   it happened to me when it did. It helped me grow   46 , confident, and strong — things I’m now hopefully instilling in (灌输) my children. Sometimes life throws you a curve ball, hands you a lemon, or knocks you for a loop (gives you a shock). But knowing how to   47   failure can be the first step to success. This is my latest belief and strategy on how to win in the end.
