>ember, there are stages that you have to follow, and make sure that the letter has killed 100%, which means that you pronounce it without stuttering using techniques, and that fear is 0% Thank you! I see, yes I understand your explanation about how to kill a difficult letter, but if we assume that a person doesn't have fear, that I'm still in the dark about what 'killing a difficult letter' means. What does it mean exactly? What do we kill in the difficult letter? Can you explain it more?
