I Peter 4:7
Be clear minded and self-controlled so that you can pray.
I need to control my own thought processes and attitudes, as well as my actions so that I will be able to think clearly, to know God's righteous will for me; and then I will be able to be of one mind with God and ask Him to do for me what He wants to do for me, to give me what He wants to give me. Then I will be able to pray. And His answer to my prayer will bring the credit, the glory to Him.
