The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.
Different for me .... i simply cannot tune in to who's speaking if there's the hum of conversation around ... it just doesn't 'stand out' for me ... even if i'm intently focussed on them i can usually barely hear them ..... so when you're in a group and the conversation is flipping between people like it does i frankly cannot track it and lose the ability to contribute
