We often talk about ourselves as if we have permanent genetic defects (缺陷) that can never be changed. “I’m impatient.” “I’m always behind.” “I always put things   31 !” You’ve surely heard them. Maybe you’ve used them to describe   32 .
These comments may come from stories about us that have been   33  for years—often from   34  childhood. These stories may have no   35  in fact. But they can set low expectations for us. As a child, my mother said to me, “Marshall, you have no mechanical skills, and you will never have any mechanical skills for the rest of your life.” How did these expectations  36  my development? I was never   37  to work on cars or be around   38 . When I was 18, I took the US Army’s Mechanical Aptitude Test. My scores were in the bottom for the entire nation!

Bob asked me how I knew I had no mechanical skills. I explained my life   42  and told him about my   43  performance on the Army test. Bob then asked, “  44  is it that you can solve   45  mathematical problems, but you can’t solve simple mechanical problems?”
Suddenly I realized that I didn’t  46  from some sort of genetic defect. I was just living out expectations that I had chosen to  47 . At that point, it wasn’t just my family and friends who had been  48  my belief that I was mechanically hopeless. And it wasn’t just the Army test, either. I was the one who kept telling myself, “You can’t do this!” I realized that as long as I kept saying that, it was going to remain true.   49  , if we don’t treat ourselves as if we have incurable genetic defects, we can do well in almost   50  we choose.
