Practice-practice-practice. Recording yourself on video and parsing feedback from your audience also helps. For example, you can take the "I speak" course.
Allowed myself to be imperfect.
I can honestly say at the beginning that I am worried. This relieves anxiety well: its signs are now legalized, there is no need to worry that they will be seen. And the audience rather perceives such recognition as a compliment (you are important to me, significant).
Of course, if after that I say garbage that nobody needs, then confession in excitement will not save, but aggravate. Therefore, one more trick - I am completely, in fact, aimed at ensuring that listeners get a result for themselves. According to the Hamburg score, I don’t care about all the officialdom, I’m here - for them and for them.
And this is what people see, and for this they forgive all sorts of errors.
I recently became to speak, - he gave an example, - emotionally he got involved in it, - and forgot what he led to, what thesis he wanted to say as a conclusion. Well and - okay - "I'm sorry, I say, I got carried away and forgot what I said. I'll remember - I'll be back!" - I continued the topic, - and from experience I know, if you don't "take a steam bath", then - I remember. I remembered - and - "Ah! That's what I was talking about! .." - and very appropriately "looped" the topic with the thesis that flew out of my head.
This actually only gives liveliness to the speech.
In a word:
1) do not be afraid to be imperfect,
2) you can say about your excitement, "legalize" it,
3) full an attitude to ensure that the audience gets the result from your speaking - and to hell with everything else.
According to Dale Carnegie's book How to Build Confidence and Influence People by Speaking in Public, the most important factors are 2:
1. You must rehearse a lot and diligently. Read your speech inside and out in front of your friends, in front of the mirror. Try to imagine the sensations you will experience on stage. This will give you a lot of confidence, and the chance that you forget to say something will decrease significantly.
This is if you have little time left to prepare. And if you have time, do not come past this book. The first 2 chapters will help you a lot.
