Also Ahmed, the most important thing you can do while planning to give a presentation is to NOT PLAN WORDS! So yes, you need to have a general idea of what you want to say, but do not plan the exact words that you will use. I would suggest writing down certain points on a card, points that you will need to discuss. Then when you do practice the speech, you will find that each time you practice it you will use different words.
As long as you get across everything that needs to be said, it does not matter how you say it. If you would like a coaching session, why don’t you sign up for coaching with one of our certified coaches? We can demonstrate exactly how to prepare for a speech/presentation. NB – Don’t think words!
