Arre, just move on to life. Yes, child hood memories may be sweet, but its no use remembering them! 
For me, the present is much better than my childhood. May seem a bit odd to you though.
Pause and turn back...
Life's not a waste.
Those who never remember the past are condemned to repeat their mistakes.
Life has much more to show, but you'll value it only if you appreciate what it has already given you.
There are happy moments to come, but they will never equal those that already passed.
Learn to search for and understand the 'why'. You did not live all the years, all the moments to just let it go away.
We never do good enough, turn back to improve on what you can do.
Keep walking... but do not forget where you had set off.
Be better, but do not forget who you were. The past is behind, let it not fade away. The future never lasts.
Pause... Look again at what you have done. Because at the end, nothing will remain, except you.
And your past.
