I was reading the script of "The Dark Knight Rises" where I encounter with a sentence
"It will be a very long time before someone inspires us the way Harvey did"
I spent some time with this sentence and arrived at the following conclusion,which is according to me. I broke this sentence into pieces "it will be a very long time before someone " which might be meaning "someone has to do a lot of hard work " ,"inspires us the way Harvey did" which might be "to inspire us the way Harvey did.
I may be wrong ,so I'd like to know the exact meaning
