Here's the first thing you have to do if you want to turn your will over to His Will and have Him lead you. You have to want to turn your will over to Him, because He cannot force this. You have to want this more than anything. You can't hold on to some decisions by yourself. Do you wake up in the morning and say "Father (or God), what will you have me do today?" Do you ask Him in each moment, for each choice you make? If you don't ask, how do you expect to get an answer? Maybe you ask and you don't quite hear the answer yet. But you have to ask first! You will increasingly be able to discern His voice versus yours, but you have to practice by asking in every moment, even for the most minor of decisions. This is called holy communion with Him.
