Totally surrendering to God means giving up your will for His. It means being the clay in the hands of a potter. It means you don’t get to determine what the potter will make with the clay, but rather you trust that you will be made for a purpose that only you can fulfill. 

God HAS made you for a purpose that only you can fulfill. Trust His molding, and even when He puts you in the kiln, the burn will not destroy you, but rather “set” you; to give you the best chance at being all that you can be.
