Step Four wants you to do the same drill, but now you should drop the hardest word in each sentence. Now you must choose. Which word slows you down the most or is the hardest to stroke? Find that word. Drop it. Move on to the next word.
Remember to keep your drill very slow. You are learning to drop. Learn to knock out all hesitation associated with the drop. Keep it smooth.
This drill is probably very irritating to some of you. Calm down. You don't have to write at breakneck speed to succeed. Rhythm, control, clarity -- those are the keys.
No fair skipping some of the steps. If you haven't put in the time, you won't progress as well.
If you have any trouble with this drill, you should repeat earlier steps.
