                                          Make Up Your Mind to Succeed

     Kind-hearted parents have unknowingly left their children defenseless against failure. The

generation born between 1980 and 2001 grew up playing sports where scores and

performance were played down because "everyone's winner." And their report cards

sounded more positivethan ever before. As a result, Stanford University professor Carol

Dweck, PhD, calls them "the overpraised generation."

     Dweck has been studying how people deal with failure for 40 years. Her research

has led her to find out two clearly different mind-sets that have a great effect on how we

react to it. Here's how they work:

     A fixed mind-set is grounded in the belief that talent (才能) is genetic - you're a born

artist, point guard, or numbers person. The fixed mind-set believes it's sure to succeed

without much effort and regards failure as personal shame. When things get difficult, it's

quick to blame, lie, and even stay away from future difficulties.

     On the other hand, a growth mind-set believes that no talent is entirely heaven-sent

and that effort and learning make everything possible. Because the ego (自尊) isn't on t

he line as much, the growth mind-set sees failure as a chance rather than shame. When

faced with a difficulty, it's quick to rethink, change and try again. In fact, it enjoys this

experience.

     We are all born with growth mind-sets. (Otherwise, we wouldn't be able to live in

the world.) But parents, teachers, and instructors often push us into fixed mind-sets by

encouraging certain actions and misdirecting praise. Dweck's book, Mind-set: The New

Psychology of Success, and online instructional program explain this in depth. But she

says there are many little things you can start doing today to make sure that your children,

grandchildren and even you are never defeated by failure.
