Answer:
Lunch Money
Life Lesson for Greg and Maura:
Making money is not a means to an end. Happiness in life does not depend on making more money per se. Happiness depends on giving out value. When you give out value, you will likely receive value in return. Sometimes, the value is monetary and some other times, it is pure bliss, i.e. the satisfaction one gets from knowing that he or she had been of tremendous help to another human being.
Importantly, creativity is a good skill which is quite emulatable. It involves thinking outside the box to marshal out solutions to people's problems with a win-win outcome.
Explanation:
"Lunch Money" was a children-targetted novel written by Andrew Clements in 2005. Its protagonist was Greg Kenton, a "shylock kind of kid" despised by Maura Shaw, who unfortunately duplicates Greg's comics.
