"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 

Do good things. Do things that benefit you and especially others. It can be as small as giving change to a homeless person or a person in need. Influence good character. If you do, others might just follow it. If you do good, you'll feel good and good things will come back to you. If you do bad, you'll feel bad and there will be repercussions. If you want the world to be filled with goodness, start doing good things. You cant make the whole world and all the people in a it good. There will always be someone who isn't a ctr person, but that doesn't mean you have to give up on being good. Take baby steps to try to make some of the world a better place, start with you. Start being a better person and the world might just follow.
