Jeremiah 1:5 (MSG) 5 "Before I shaped you in the womb, I knew all about you. Before you saw the light of day, I had holy plans for you: A prophet to the nations—that's what I had in mind for you."

YOUR PURPOSE IS NOT YOUR CHOICE - ITS EMBEDDED IN YOUR DNA - ITS GOD’S CHOICE - FIND IT 

UNTIL thought is linked with purpose there is no intelligent accomplishment.  Refuse to allow your thoughts to continually drift without aim.  Foolish and purposeless thinking will get you no where. Get your life in the right direction through purposeful thinking.
