But why is self-awareness considered precious? Isn't it natural for a person to understand themselves?
Can I truly control my body? Can I truly control my thoughts? Can I truly control my actions?
Do I know what I am doing? Do I know what I want? Do I know what my principles are?
Is it only at the age of thirty that I will come to know?
(Note: "三十而立" is a Chinese saying that translates to "At thirty, one should be independent and established." It suggests that by the age of thirty, a person should have a clear understanding of themselves and have established their principles and direction in life.)
