I like how you phrased that as the positive result of a (personal) growth mindset. For non-native English speakers, the word "grit" might be interesting to learn about. Aside from the other common meaning of "coarse grains as of sand or stone"..
> In psychology, grit is a positive, non-cognitive trait based on a person's perseverance of effort combined with their passion for a particular long-term goal or end state (a powerful motivation to achieve an objective).
> This perseverance of effort helps people overcome obstacles or challenges to accomplishment and drives people to achieve.
> Distinct but commonly associated concepts within the field of psychology include "perseverance", "hardiness", "resilience", "ambition", "need for achievement", and "conscientiousness".
It reminds me of a similar term, "gumption".
> gumption - Boldness of enterprise; initiative or aggressiveness.
