It is important not to allow ourselves to be put off by the magnitude of others' suffering. The misery of millions is not a cause for pity. Rather it is a cause for compassion.
Whatever suffering there is in this world,all arises from desiring only myself to be happy.And whatever joy there is in this world,all arises from desiring to share my happiness with everyone.
I think the person who has had more experience of hardships can stand more firmly in the face of problems than the person who has never experienced suffering. From this angle then, some suffering can be a good lesson for life.
