Do one thing at a time. When practicing the form put all your effort, focus and concentration on the single technique your practicing before moving on to the next. See how the whole body is engaged in that movement, see how your posture is, what part of the body moves first, where the power is coming from and how the momentum is engaged to execute the move. Slow down even more and focus on each body part one at a time as you move. Then put it all together at the proper pace.
The sharper the sword, the less effort is needed by those who wield it.
