Teenage Dream by Katy Perry This is saying to take chances in life and not to regret them. Once you make a choice, you can't change it, so you might as well keep your head facing forward and keep moving on.
Don't expect people to understand your direction in life, when God didn't give them your vision. You're going to know when it's from God. No matter who tries to run from it. God sais no. Not this time. And removes EVERY person that gets in the way.
