There is no wasted journey in life, every step counts.
不要害怕失败，要害怕不去尝试。
What we know is little, and what we are ignorant of is immense.
Wisdom acquisition is a moral duty.It's not something you do just to advance in life...You are not going to get very far in life based on what you already know.You're going to advance in life by what you learn after you leave here.
