My way or the highway

I don't like the idea of leaving it up to God to decide how life will be lived optimally for me. I'm worried he's gonna choose a life for me that I don't like, that I don't want. I know what I want, I want this and that, most of which is not compatible with a Christian life. What if I don't want to do what God has planned for me?
Solution: Don't ask God to change your life, ask God to change your heart, so that you'll want the things he want. What if I don't like it? You will, cause when he changes your heart, his way is exactly what you'll want:)
