Editing The PastIt's easy to look back

It's easy to look back
At what I've done before
With some pride and often shame
Never quite the same

There are typos, there are flaws
In melodies and thoughts
They show the path I took
My worlds open like a book

Chapters telling tales
Music flowing scales
And I still have the source

I know now what to improve
What to change and what to move
History must run its course

The flaws were mine in deed
Each a valuable seed
To grow.
