Jehovah warned mankind in Jeremiah "I well know, O Jehovah, that man's way does not belong to him. It does not belong to a man who is walking even to direct his step." Jehovah God isn't an option, He's a necessity!
There is no such thing as an unanswered prayer, Gods answer is either Yes, my child. or its No, child I have something better for you. so when you dont get what you thought you were wanting just think, Gods plan is better for you. He wont lead you astray.
