"Even if everyone is doing, WRONG IS NEVER RIGHT." Russell M. Nelson 

Wrong is wrong. If everyone in the world is doing drugs that still makes it wrong. No matter if the president does it. If the whole school is cheating besides you that doesn't makes it right. Be a leader not a follower. Lead people into not doing wrong. Lead them into doing what is right forever. By doing right things the world would be a different place. The more you emphasize it the more people will begin to follow you. Do great things perform random acts of kindness. Most importantly don't let yourself down and don't pay attention to what others do.
