Finding something bigger than your fear, greater than your anxiety, is a key strategy to get rid of the natural negative emotions.
When you talk about something you are passionate about, the words come naturally, in a flow. Even if the words are forgotten, you can easily bounce back, as your inner fire won't let the words fail you.

Finding out what works for you to give your best presentation is important. Make a list of what you have to do in front of the audience and go over the list to help you remember.

If you are still feeling afraid, you need to face your fear and make yourself comfortable with the fact that it's not the end of the world.

Certain relaxation techniques like deep breathing, or speaking slowly, calm us and get us out of our irrational fears.

Speaking slowly is also better than speaking at a fast rate, which can make you lose your breath, showing the audience that you may, in fact, be scared.

Trying to be someone else, or copying someone's style can show in your presentation.

Being yourself makes you speak from your heart, with your beliefs and experiences coming out. Speaking the truth, and being honest is freeing, and can give your presentations more power.
