Answer:
Even though we experience growing-up moments, we need to act upon the lessons we learn in order to grow up.
Explanation:
Jessie McBirney's "Growing Up: Key Moments" provides an insight into how a person gets mature or 'grows up' not because of an increase in age but more from life experiences. The article explains how life's experiences would often become the building blocks of one's growth.
The author connects how a person's actions and his growing up moments by pointing out how growth is more of experiences rather than the number of one's age. And through the happy and painful experiences, one can also experience or attain growth by learning from such events.
Thus, the correct answer is the third option.
