At thirty I live my own life.
In analects of Confucius, there are the words as follows.
"At fifteen I aspired to learn. At thirty I lived my own life. At forty I had no doubts."
I think I cannot understand "to have no doubts" unless I understand "to aspire to learn" and "to live my own life".
First of all, I want to ask myself what is “to aspire to learn” and “to live my own life”.
