Do you believe that the best leaders are born, not made? What about musicians, artists, mathematicians?
Do you believe that there are only talented people and people with no potential to be stars? That's a fixed mindset.
If we think of ability as fixed, we discourage learning, practice and resilience. Could you be doing the same to yourself?
Yes and no. Yes, if they come with mini-goals and an action-based plan to achieve them. No, if the ambitious goal is really just a dream or fantasy.
