I Learned From You
OST. Hannah Montana
Miley Cyrus and Billy Ray Cyrus

I didn't wanna listen to what you were sayin'
I thought that I knew all I need to know
I didn't realize that somewhere inside me
I knew you were right but I couldn't say so
I can take care of my self, yeah, you taught me well
I learned from you that I do not crumble
I learned that strength is something you choose
All of the reasons to keep on believin'
There's no question, that's a lesson, that I learned from you
We always don't agree on
What is the best way
To get to the place that we're going from here
But I can really trust you, and give you the distance,
to make your decisions without any fear
I'm grateful for all of the times
You opened my eyes
I learned from you that I do not crumble
I learned that strength is something you choose
All of the reasons to keep on believin',
There's no question, that's a lesson I learned from you
You taught me to stand on my own and I thank you for that
It saved me, it made me, and now that I'm looking back
I can say I learned from you that learned from you
I do not crumble
I learned that strength is something you choose something you choose
All of the reasons to keep on believin', keep on believin'
There's no question, that's a lesson that I learned from you
Woooaaahhhh !
I learned from yoooouuu
I learned that strength is something you choose something you choose
