Does a solution change the world?

A week ago I was talking to a prospective client and we were trying to figure out how I can help solve her problem.  After a short conversation I asked her my starting question,

"What is the problem I am trying to solve?"

She looked at me and stated, "I want the students to write better."   Even though this was a pretty big goal, but it was a place to start.

"Starting with the end in mind"

that sounded familiar but I could not remember where I remember hearing it.  A quick Google search provided many references to the phrase, but after scolling through the Ad-bosted links I saw where I origninally heard the phrase.  It was in the book, The 7 Habits of Highly Effective People, by Stephen Covey  The Habit 2: Begin with the End in Mind.
