Joseph Campbell says it well
"We must be willing to let go of the life we’ve planned,
so as to have the life that is waiting for us.”
"Oh, well... I thought that was what I wanted, but it isn't working out that way, so I will stop trying to make it happen, accept it and move on to what God has in mind for me." When you give your plans to God, you can rest assured that he will guide and it will happen and be right and good and successful; because He keeps his word and He can do anything. He is GOD, after all! "For nothing is impossible with GOD." Luke 1:37
Proverbs 16:3 says it even better
"Commit your works to the LORD, And your plans will be established."
