Dear Gloria,
in http://www.heavenletters.org/dreams-keep-you-going.html
paragr. 8
"And, as Edison, plied his dream, he enjoyed his working on it. Make sure that you do. If you do not enjoy working on your dream, maybe it isn’t really your dream. And that’s all right too"
I don't understand the grammatical structure of this first sentence, especially "plied his dream". Can we "ply a dream"? Should I read: "And, as an inventor, Edison must have worked very hard but he enjoyed his working on it" ?
Thanks
