“ It is 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

this quote means  that you should focus on the things that are good in all different ways, you should not focus on the bad influences. This is true because if you keep thinking in bad things they will bring you down and not let you succeed. For example people should promote each other for doing the right things. We should also promote those things that sounds good , because it will make us look better. Another example is the for school we need to wear uniform and to promote our school to make it look good we follow the rule. No matter what be a CTR person.
