nice question. a question that is hard to be answered. but i will answer it in my own way. for me, let say we're talking about a country. the leader must do the right thing. even if the country is full of bad people or heartless people, the leader must solve them in a good way. some followers will follow the rules but some of them are the rebels. and that's the problem. when the rebels are doing some bad things to destroy the world, the leader must do something. not just the leader, even us, as the human with brain have to help our brainless fellows. so in this, heart and patience is important. what can we do to help the world? be a useful person, use the brain. use the heart. patience! God's willing, if all of us, all the people from all places, countries and what ever, remember. use your brain. be patient. especially the youngsters nowadays, SWAG or "YOLO" is not important if you do not know how to use your brain in a right way. make a good group, a good society.
There is a lot of things that you can do. For starters if you are seeing someone being bullied at your school don't just sit there and watch. and think oh that person's going to be okay because he / she most likely won't be. Take a stand stand up for that person don't back down just because your afraid you might be bullied it is part of taking a chance. Also find some activities that you can do around your neighborhood. There is always volunteer work and helping those in need. The list goes on and on.
