‘’ It’s our duty to concentrate all our influence

to make popular that which is sound and

good, and unpopular that which is unsound’’

(not good) -Joseph Smith

What this quote means is that you want people to think good things about you. That it should sound good. This also means that you have to influence people in a good way. Also this might mean that others might see that you don't care about your education and they might start feeling the same way and will do the same thing this would be making what you do popular. And if you are staying on track and not doing bad things then others will see how you are doing good. This would be making what you are doing popular as well.
