Take this first little step!
Are you worried about how to make effective presentation? Are all your efforts to make effective presentation is in vein. Just follow these tips:
Consider how you make a normal conversation with your friend about the last movie you have seen. You have not prepared anything to talk. Your mind naturally fetch the ideas you had in your mind and present to you to converse with your friend about the movie. Ideas are conceived in our mind rather than just in terms of words.
But when it comes to presentation of any topic related to our subject or any technical aspect, we block our mind with the fear of presentation and do not allow our mind to think naturally about the topic. Think in terms of ideas of your talk not in terms of words. If your presentation is about a one page content, break those contents in terms of ideas. Let ideas be recollected in your mind.
