In fact, the first half of this sentence was said by the great inventor Edison. He said, "Genius is 99% sweat and 1% inspiration", and the latter part is added by others, "and success is often the last one".

We cannot deny the so-called inspiration and talent. The most well-known story is that Newton was hit by an apple, discovered the law of gravity and became a giant in physics. The inspiration from being hit by an "apple" is really important, but imagine what would happen if he just thought about it and didn't work hard? I'm afraid this giant will be done by someone else.

So Mr Edison is right to emphasize that hard work and sweat are more important than inspiration. The second half of the sentence was just added by boring people. It seems reasonable, but it is specious.

Extended data

Mr. Edison has such a record on English Wikipedia: None of my inventions is accidental. I saw a valuable need being met, and I tried again and again. What it cooks. In the final analysis, it is one percent inspiration and ninety-nine percent perspiration.

None of my inventions happened by accident. When I see a social demand worthy of people's energy and material resources to meet, I will do experiments again and again until it is realized. This is ultimately attributed to one percent inspiration and ninety-nine percent perspiration.

Genius is one percent inspiration and ninety-nine percent perspiration. Therefore, a "genius" is usually just a talented person who has done all his homework.

The first half of this version is the same, and the second half is to the effect that "therefore, a genius is just a smart person who can often finish his work". Nor did he say "inspiration is more important".
