Carrying my Past with Me?

There are many streams I have been
Which became the river I am now
Though still the waters I was then
Yet, I am different somehow

I carry with me all the mud
And dirt I stirred before
And yet I can choose to let it go
And make sure I don't stir more

My waters are infused with the goodwill
Of hearts I've touched in the past
These gifts are mine to carry along
They are blessings that will last

I cannot say it was not me
Who did the things I did back then
But I also know it is not the me
Who is writing now with this pen

I want to carry very lightly
The baggage of my history
And not let it dominate the colours of
Today's unfolding mystery
