In other words, you need to know what kind of reaction your strike or strikes will bring so that you can act accordingly. Embracing change is the ability to accept change in order to increase your knowledge. You now have a choice - will you turn around and go back or will you continue on and learn a new route. This new route can either be accepted or rejected. But in any case you have grown through the experience.
Flow is the continuation of movement with the absence of hesitation.
First you must remain relaxed in order to achieve smoothness. You take a series of moves repeating the same pattern until the movement becomes natural. You may want to start out with four to five combinations and add as you progress. It is through the constant repetition of these movements that you will develop flow. It is my recommendation to make your movements circular when drilling, avoiding pauses between each move.
