having no expectations

does having no expectations mean no disappointment? it seems to be that case for me everytime. when i expect something to go my way and it doesnt happen, i get really disappointed. maybe i shouldnt have any expectations from anyone and accept whatever that comes...i should be able to feel better that way. maybe i should just change myself, my thinking and the way i feel about things then will i become a happier person and not expect others to change to make me feel happy.

when asked during an external course what's our happiest moment in life? i couldn't think of any. i want to be happy but i am not making myself happy. the fault doesnt lie with others, it lies with myself. how can i make others love me when i dun even love myself?
