Practise on family or friends
As a LinkedIn Pulse article states, a good way to lose the fear of public speaking is to practise on friends and acquaintances. You might, for instance, tell a short story at a family gathering, present holiday photographs or try to give your "real" presentation. It is also a good idea to deliver the presentation in front of colleagues and your manager.
Talking about topics you care about
When carrying out the routine described above, it is good to stick to topics you care about so that you really enjoy your presentation and focus properly on content rather than what you look like. Likewise in your real presentation, ideally focus on topics that interest you or that you are enthusiastic about, as then it will be much easier for you to engage your audience.
Thorough practice
Regarding your first presentation in front of a real audience, this is no time for heroics. So forget about speaking spontaneously: you might end up facing the audience not knowing what to say and ultimately forget many important points. You should learn your presentation verbatim, especially the beginning, which is psychologically the most challenging part.
Shifting your focus to the audience
When giving the actual presentation, try to shift your attention away from yourself, what you are saying and what you look like to the audience. Pay attention to their facial expressions, try to engage them and forget about the fact it is you who is standing in front of them.
Non-verbal communication
Nervousness, uncertainty and fear are states of mind whose non-verbal signals are hard to conceal. On the other hand, if you learn to use non-verbal signals which, on the contrary, show self-confidence, you will seem more confident not only to your audience but also to yourself. This is why you should stand upright, chin up, shoulders back, open stance towards the audience, no shuffling or fidgeting.
