Just Do It
The conscious mind is surprisingly slow, conscious choices and actions are delayed for a significant time (a reflex acts within some tens of milliseconds, an unconscious reaction to external stimuli circa 100 milliseconds and a conscious choice several seconds). The duty of the conscious mind is usually to inhibit rather than start action, and if you become too conscious of what you are doing in a tense situation you will hesitate or slow down.
It is a good idea to learn to rely on your non-conscious mind, since our conscious mind is slow and has very low bandwidth while the other systems in our brains have a tremendous capacity and actually do most of the real work anyway.
