人生没有白走的路，每一步都算数。
There is no wasted journey in life, every step counts.
Success in this industry requires both vision and execution.
You have to be willing to sacrifice what you are for what you will become.
因此，教学艺术无非是时间、科目和方法的巧妙安排。
Failure is not a bad thing. It's part of the process of learning and improving.
