I believe that money is the root of all evil.. I think if we just care about humanity, not luxury and money, there will be a better world. Change should start on ourselves. Honestly, if you want change the world, you should start from yourself . You should have a discipline. Think about what can you give to our society to make it better. Build a business, give opportunity to the jobless people, hire them. Something like that. That makes your life purposeful.
