I take this one as a (wonderful) 'poem' about becoming older&mature, but not necessarily under a sad perspective if you are a realistic person... I mean he's saying to us for not trying to hold our oldest&precious memories in an obsessive way as expecting all those magic events could happen again, but for leaving these same memories come to our mind only for bringing light to our lives, for making us smile, for turning us less serious than we are at present... Then we become gold again.
