We can choose to let our subconscious work for us, or against us. Peter Senge writes in "The Fifth Discipline" about the subconscious:
"...many people committed to continually developing personal mastery practice some form of meditation. Whether it is through contemplative prayer or other methods of simply quieting the conscious mind, regular meditative practices can be extremely helpful in working more productively with the subconscious mind. The subconscious appears to have no particular volition. It neither generates its own objectives nor determines its own focus. It is highly subject to direction and conditioning - what we pay attention to takes on special significance in the subconscious. In our normal highly active state of mind, the subconscious is deluged with contradictory thoughts and feelings. In a quieter state of mind, when we then focus on something of particular importance, some aspect of our vision, the subconscious is undistracted."
He goes on to say that people with high levels of personal mastery direct their focus on the desired result itself, rather than the process or the means they assume are necessary to achieve that result.
By visualizing the desired result, the subconscious rolls up its sleeves and gets to work on focusing and prioritizing. And it all starts with some form of meditation.
