I see my upbringing as a great success story. By disciplining me, my parents inculcated self-discipline. And by restricting my choices as a child, they gave me so many choices in my life as an adult. Because of what they did then, I get to do the work I love now.

This quote is about how the person’s upbringing has been very successful in helping them define the path the person has taken in life.
