²⁶Likewise the Spirit helps us in our weakness; for we do not know how to pray as we ought, but that very Spirit intercedes with sighs too deep for words.²⁷And God, who searches the heart, knows what is the mind of the Spirit, because the Spirit intercedes for the saints according to the will of God.²⁸We know that all things work together for good for those who love God, who are called according to his purpose. Romans 8:26-28

Spend at least15-20 in silence.  Find a comfortable place with as few distractions as possible.  Work on clearing your mind.  Count your breathing if you need to, but clear your mind of the to do list.  Let your thoughts wander to a place of serenity and calm.  Let the Spirit intercede for you.
