I searched on GOOGLE about this issue, and one of the comments was like this:
This is what it says at the beginning:
Inspiration and Perspiration
By Cindi Myers
Thomas Edison said, "Genius is one percent inspiration and ninety-nine percent perspiration."
Without the one percent of inspiration, all the perspiration in the world is only a bucket of sweat....
The translation of this last paragraph is very close to the extended version of the famous saying in the original text. It must be one of the original theories. According to. However, what no one can ignore is: "No 1% inspiration, all sweat..." This sentence is not within the quotation marks of Edison's famous quote!
Note the title above
Inspiration and Perspiration
By Cindi Myers
It has been clearly stated that this article was written by Cindi Myers argumentative essay. So the words outside the quotation marks are just a comment from Cindi Myers.
I think this is the end of the study, and the source should be here. The author of the original article started on the wrong argument. However, in my opinion, the argument is a good one...
Original English words: Thomas Edison said, "Genius is one percent inspiration and ninety-nine percent perspiration."
