Certain

My life is an open book of changes and this just occured to me
I dream of all these different places that I would rather be
I know that all I want is to be a man who is certain with himself
My battles aren't won [2x]

Until I'm certain with myself it's hard for me to feel this anymore
Where have the feelings gone I need to stop myself from hiding
I've been down for far too long I know these worries of mine
They won't change like the world I'm in
How do I change myself?
