People who stutter even without fear have difficult letters or words that they have to kill first ,then they gradually kill difficult situations, and I explained this in my book (How to Kill Difficult Situations). Because you can kill difficult letters through techniques, it will become easy to say thise difficult letters or words or sentences with family, friends and strangers. But it will become difficult with your manager at work or with your teacher, for example, because you did not practice the techniques with them, and you didnt kill thise difficult situations. That is why it is important to kill difficult situations after killing difficult words in the right way. I'm going to ask you a question: We can at least say a word or a sentence with everyone without stuttering. For example, the word "yes" or the word "no", why don't we stutter in it despite all the difficult situations or even if all people are looking at us? Because these words are easy. All our lives we say it is possible without stuttering, so we are not afraid of it. With practice.. all letters, words, sentences and situations will become as easy as drinking water.
