“Unfortunately, people often like the things that work against their growth. . . . People like to use their strengths . . . to achieve quick, dramatic results, even if . . . they aren’t developing the new skills they will need later on. People like to believe they are as good as everyone says . . . and not take their weaknesses as seriously as they might. People don’t like to hear bad news or get criticism. . . . There is tremendous risk . . . in leaving what one does well to attempt to master something new.” And the fixed mindset makes it seem all that much riskier.
