It's natural to feel nervous when giving a presentation. You're not sure if the people you're working with will stay attentive, or if they'll even understand what you're saying.

The trick, as it turns out, is to grab your audience's attention in the first 30 seconds of your presentation--otherwise, you'll lose their attention for the rest of it. This is known as the "30-second rule," and it's your secret to presentation success.

How do you create and deliver a great presentation? It's not as hard as you might think. Check out these 3 tips:

1. Brainstorm ideas with your team

As you design your presentation, brainstorm feedback and ideas with your team. It'll instantly encourage everyone to be involved and engaged. Write down all these ideas, even if you're not sure how they'll fit into the grand scheme of things later on.

2. Create your 30-second pitch

After brainstorming, you'll have a better idea of what you're looking for and what your audience wants. With this focus in mind, you can create your 30-second pitch--the beginning of your presentation that will gain your audience's attention and keep it. What's the most important part of what you'll be covering today? Why? Let everyone know right away so that they're more inclined to pay attention.

3. Connect and illustrate your ideas

Illustrations and graphics help people grab onto concrete visualizations of your ideas. They also allow you to travel from one point to another, transitioning from your last idea to a new one, for example. Make sure to refine and smooth out bumpy points in your presentation, as that's likely where you'll lose people, in the logic or flow.

Be energetic, concise, and as enthusiastic as possible in the first 30 seconds of your presentation. Even though it may seem daunting, just know that--if you can hook your audience in that brief span of time--you'll be able to maintain their attention for the rest of your presentation.
