The more you think about your own self, the more self-centred you are, the more trouble even small problems can create in your mind. The stronger your sense of 'I', the narrower the scope of your thinking becomes; then even small obstacles become unbearable. On the other hand, if you concern yourself mainly with others, the broader your thinking becomes, and life's inevitable difficulties disturb you less.
Dalai LamaThe most important thing is to have a sense of responsibility, commitment, and concern for each of our fellow human beings.
Dalai LamaHuman beings are not intrinsically selfish, which isolates us from others. We are essentially social animals who depend on others to meet our needs. We achieve happiness, prosperity and progress through social interaction. Therefore, having a kind and helpful attitude contributes to our own and others' happiness.
Dalai Lama
