What does it mean to know your destiny at fifty, listen at sixty and obey the rules at seventy?

Source: Chapter Two of the Analects of Confucius said: "I am determined to learn five out of ten, stand at thirty, not be confused at forty, know my destiny at fifty, listen to my ears at sixty, and do what I want at seventy, without exceeding the rules."

I/kloc-started studying at the age of 0/5, and I can stand on my own feet at the age of 30. I'm 40 years old, and I'm not confused. At the age of 50, I understood what fate was. At the age of 60, I can listen to different opinions. At the age of 70, I can't do whatever I want, and I haven't crossed the line.
