Nostalgia

I composed this poem for an English Versification competition... Please tell me how it is. (the topic was Nostalgia)

As I look back on my past,
The memories come back to me so fast.
Good things that just had to happen,
Bad things that made my spirit dampen.

I saw myself flash before my eyes,
Sometimes laughing, sometimes crying.
I saw my childhood, full of lies,
So many promises, most of them dying.

"Look at all the good things"
I seemed to tell myself.
So I walked left quickly,
Toward the 'Good Events' Shelf.

Well, it was all there,
The happy moments of  my life.
I saw myself, full of laughter,
Around me, there was no strife.

I spotted myself somewhere, smiling,
'twas the first day of school.
On my face broke a widespread grin,
As I jumped into a large pool.

I flipped through all my good memories,
All of them making me smile.
They somehow gave me wonderful strength,
To run through life, mile by mile.
