When everything seems hopeless, consider the stonecutter who strikes a rock over a hundred times without seeing a crack, only to split it in two on the 101st blow. This teaches us that the breakthrough is not caused by that final strike, but by the accumulation of all previous efforts. Therefore, once you have set your mind on a goal, do not easily give up, for success is often just around the corner.
During high school, students must possess strong self-discipline, which can be called "mental strength." As the ancients said: "When a person is calm, they find peace; from peace, stability; from stability, wisdom; from wisdom, insight; and from insight, attainment." If one always makes excuses to delay studying due to the weather or season, such as "Spring is not the time to read, summer is too hot for sleep, autumn has mosquitoes and winter is cold, so I will wait until next year," the foundation of learning will never grow strong. Only by calming the mind can one achieve stability and eventually gain wisdom.
Tsinghua University advocates the academic ethos of "Action is superior to words," which is also my motto. I hope to share this with my fellow students. A true marathon runner will not wait for an Olympic gold medal to fall from the sky; they run. So, take action now. I am waiting for you at Tsinghua.
Learning is a process of perseverance; stopping and starting leads to little achievement. It is like boiling water: if you stop at 80 degrees and let it cool before heating it up again, repeating this cycle wastes both energy and electricity, and you will rarely get hot water to drink. Similarly, mastering any subject cannot be done with just three minutes of enthusiasm. One must maintain momentum and persist day after day. Over time, whether it is top academic ranks or your ideal future, they will come within your reach.
