My Jar of Mistakes | (Would really appreciate finding any points i could improve on! The prompt isn't original, i found it on Pinterest.)

On my desk, there's a jar,

My very own jar of mistakes.

It's full of old, embarrassing part,

Of my life—i'd dare never partake.

It stares at me throughout the day,

Come night, never let's me sleep.

It's like a great, predatory bird,

My peace's demise.

Yet one day, when I'm all grown,

I'll look at again.

Instead of anger, instead of hurt,

I'll find in it a bane.

It'll remind me of the time,

Passed,

The girl I used to be.

The very faults i wish to hide,

Will,

One day, bring me peace.
