Fixed or growth mindset — which do you have?

    We live in an uncertain world with all the technological advances we are experiencing, which meanse is a requirement for a change in midset (思维模式). In order to be on top of our game both personally and organizationally, we need to develop a growth mindset.

    A fixed mindset supposes that you have native abilities and are naturally clever or skilled in certain areas of life. When you receive infonnation about how you have performed in a test or set of tasks t you may worry about how you are judged. Our parents probably said to us when we were young,"Since you scored really well in the test, you must  be clever." However, by being repeatedly told “You are clever” or “You are really good at your job”,a person's self—respect is actually dainagcd.

    The  growth—mindset  person a view life as a series of exciting challenges and  want  to constantly  learn. Brain activity occurs in this mindset when they receive information about what they could do belter or improve. They do not view their abilities as fixed or us failure. Learning is king and the more they practice , the more they know they will succeed.

    What is important is giving praise around process and not around ability. For example , instead of saying"Since you got a great score, you must be clever" f say " You got a great score, and you must have tried really hard". This creates challenge in individuals and the meaning of mindsets is massive for business. Fixed-mindset managers are not fans of giving feedback (反馈). They do not want to stretch themselves or others because they fear failure. Therefore their business may stand still because there is no risk or innovation (创新) occurring.

    Listen from your own fixed mindset — for example ," I can't  do that” — and answer with a growth-mindset response — “I can't do that yet!" Remember  there is no such thing as failure and there is s only learning. If you don't fail occasionally ,you will never learn to change and grow.
