Sit alone and ask yourself to see how many people will have different difference after your death? Take care of those people who have differences.

Over time, you become tolerant when you start accepting people for who they are, when you understand that they can be completely different from you but still be amazing in their own right, when you feel sorry for them. 

 When you understand that you may not have all the answers and that there are always other sides to every story, when you learn that some things are out of your control, acceptance. The hardest but sometimes the only way, when you cherish your lonely moments, when your peace of mind is most important, when you regret the things you thought were worthless, When you realize that pain is the best teacher.

 This is when you learn that your own "moral consciousness" should never stop you from doing the right thing.
