Moments of Clarity: The Who?

Sometimes I think of who I used to be,
Then I remember I've done no wrong,
She remains a part of me,
She's not forgotten,
And she's not lost,
She is a fragment of the whole,
Yesterday she shaped me into who I am today,
Tomorrow I'll be more,
Determined to be the best version of myself I could be,
While remembering that flaws define our very nature,
They are scars from lessons learned by who you were yesterday,
I will be who I will be tomorrow,
Because of who I am today.
