Summary
This quote suggests that a person's age should not be determined solely by the number of years they have lived, but rather by the state of their mindset. It implies that as long as an individual continues to hold on to their dreams and pursue them actively, they remain youthful and invigorated. However, once regrets and a sense of complacency overshadow their ambition and passion, it is then that they become truly old. It highlights the importance of maintaining a positive and forward-thinking attitude in order to stay young at heart.
