Genius is 1% inspiration and 99% perspiration.

The second half of the sentence is "But the 1% of inspiration is the most important, even more important than the 99% of sweat." The Chinese textbooks have all been deleted, but I personally think the two sentences are equally important. Just reading the first half of the sentence can easily lead to overestimation, while only reading the second half of the sentence can make people lose the courage to delve deeper. Both sentences are indispensable. This is probably why among hundreds of inventors working on electric lights, only Edison succeeded.
