Nine times out of ten, you are determined to learn, you are not confused at forty, you know your destiny at fifty, you are obedient at sixty, you are willing at seventy, and you don't overstep the rules. I didn't decide to study until I was fifteen, and I didn't get confused until I was forty. At the age of fifty, I knew that fate was hard to break (meaning that I would not live long). At the age of sixty, I felt that my self-cultivation was mature and I could take it lightly. At the age of seventy, I can finally do what I want without breaking the rules. Knowing yourself, you can't guarantee that you are all right, but you still have some confidence in your ancient prose. )
