The jealousy that arises from another's achievement is overcome by developing an awareness of and admiration for one's own and other's achievement.
Dalai LamaHappiness cannot come from hatred or anger. Nobody can say, 'Today I am happy because this morning I was angry.' On the contrary, people feel uneasy and sad and say, 'Today I am not very happy, because I lost my temper this morning.'
Dalai Lama
