How are we going to improve this world? I think every person can change this world. But you really must want it. Firstly, we can help people and animals. For example, many people need some help - people who are in hospitals, old people, disabled people, homeless people. But I understand that not every person can help people who terminally ill because it's very difficult. But there are many problems in whole world which you can decide if you would want. I suppose even a small thing can be beneficial for someone. I think it's not difficult to say someone a couple of kind words or, for instance, carry a bag. You don't need money for your helping - you have an enormous inner potential to do it. I'm sure if we simply are patient and kind, our world will get better.
