Unblocking.
If a water pipe is blocked, you don't keep staring at it and hope it will unblock itself. You would need to do something about it. Maybe you do it yourself or you call a professional. But, there needs to be some movement.
The same is true with the blocked mind. It requires movement to unblock.
Whether it is the movement of your fingers over the keyboard, a long walk, or the movement of your body to music, once you start moving, your nervous system starts unblocking too.
And as with the water pipe, sometimes you need the help of a professional to get the water flowing.
