+ Past has pass me +

what past is past.those we must live,continue to live..there is no transport can take us back to our past which mean,past is so far away where we could not comeback..but past has teach alot of meaning in life,but why until now it seems not enough..sometimes i feel like i've done my best,but back then i think back is dat the best i could do.. i as a normal human,wanna live a happy life,but whats the meaning of happiness without sadness in it..sometimes it came back in my mind..about past..it has a lot of story and past..has pass me very far away..
