“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

I think this quote means that the simpler the better. People who wanna be popular never do good. For example, if someone wants to join a group and the group member is telling them that in order to be in it they have to go do something bad and the person does it, consequences will end up bad. But if you always do good and sound good you’re choosing the right.
