New Found Glory Certain lyrics

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
