It will take time and practice so that your subconscious mind rather than your thinking mind is performing the task. If you are thinking about every little move and position your muscles will not work smoothly and effortlessly be it a golf swing, carrying a plate of soup across a room without spilling a drop or stropping a razor. If your mind is thinking what to do during the task it is not allowing the process to flow as it should. Just keep practicing and eventually you will get there and it will be effortless.
