However , just like Murphy's law anything that can go wrong will go wrong. The first thing that went wrong was instead of the 30 minutes for the talk my supervisor said it would be 15 minutes. Second, the air conditioning system decided to break down on that day, everywhere was so hot and you could see that my colleagues were visibly uncomfortable. Third since I was going to be the last speaker they had already had a heated argument about something that went on in the office the previous week. It was crazy.
I am sorry to hear that and sorry to say this, but you were just unfortunate with the situation. Your situation at that time was bad enough. That is why it's driving you to a condition like that. However, if I were your colleague, I may also be in the same situation. Our brain may have been very hot and super pressure because of the previous meeting discussion and with that uncomfortable place and ambiance, this will really worse the situation. Moreover, if we are going to get something very new, this will really influence your mood to accept it.
I know by then the AC would have been fixed but I want to ask members of this forum how do I overcome stage fright in my next meeting? This right now is my biggest worry and concern. I do not want to mess this up again.
Then, you should be relieved at first, moreover, you are given the second chance, and this is a very good chance for you to make them excited. You may not need to expect all people excited about what you are going to say, but at least, you are trying to ensure them and get their interest first. Because in the next meeting, you may also face quite similar conditions where they have been having previous discussions about other serious things, and they may be again not in a very good mood. So, what you need to do is first by ensuring yourself not to be fright. Actually, stage fright is very normal and happens to most people, moreover if that is the first time. but, you can train it and ensure you are ready with what you want to explain. Secondly, make the situation of the discussion and meeting lively up and cheer up again so that they can put aside their previous discussion and get new brainstorming. You may not need to teach them a very technical discussion about Bitcoin with a serious explanation because this will make them bored during the explanation. You may need to explain with something fresh, easy examples and proof, or with something that cheers up the room, that is suitable for the audience of course.
