To be self-confident is to trust in our own abilities and believe that we can do what we set our minds to. Carol Dweck’s research at Stanford University changed the way that we think about success. In her book, Mindset: The New Psychology of Success, she revealed the difference between a fixed mindset and a growth mindset. A fixed mindset assumes that our intelligence is static, meaning that it cannot change. Avoiding failure at all costs is the name of the game. Conversely, a growth mindset thrives through adversity. Failure is viewed as an opportunity to grow and stretch oneself.Healthy self-belief is not narcissism, bragging, or boasting. Rather, it is a realistic but optimistic evaluation of yourself and your abilities and a sense of trust and confidence in yourself.
