Moving forward and not looking back

i guess there are many times in which I'm tempted to look back, but when i really think about it... maybe it's best that the past is left as the past.... though sometimes my heart feels like it's left behind... i finally realise that i no matter what i'm determine to move forward... i've come too far to turn back again... i've finally found happiness and i'm not willing to go back again... i'm much too different to fit back into a box that i once left...
