School motto on the self-study wall of Harvard University Library. Now you take a nap, you will dream; Study at this moment, and you will realize my dream. Today, which is deserted at the moment, is precisely the time when the people who died yesterday pray that it is too late for tomorrow. Don't put off today's work until tomorrow's study, it's just the best time. The pain of not learning is lifelong learning, not lack of time, but lack of effort and happiness, but success will rank second. Learning is not the whole of life, but since even a part of life-learning-can't be conquered, what else can we do? Please enjoy the inevitable pain. Only by working harder than others can we taste the taste of success. No one can succeed casually. It comes from thorough self-management and perseverance. Time is passing, and the saliva dripping now will become the tears of tomorrow. Study like a dog, play like a gentleman, don't walk today, run tomorrow, and invest in the future to be loyal to reality. Education level represents their final income, but not.
