Doing the right thing is just doing what is known as being right, but being smart has to do with doing things rightly. Being smart doesn't have to been tagged as being dubious, one who does things smartly has an edge over others because they do not just know the right thing, but consider the best alternative that suits the challenge at hand before making decisions. Sometimes you can do the right thing but it may lead to complications but then someone else might have that same knowledge and do it smartly without compromising standards so as to avoid problems. With your personal morals intact, you wouldn't consider a short cut or fraudulent acts as being smart.
