Simplicity will gain confidence.

*One of my freelance job which I had to give the presentation for the Surface Pro 3.*

In fact, to make a good presentation is 

The simpler your idea and the simpler your presentation of it,

then it will more likely you are to emerge the winner.

Winners instinctively know that to make something big happen, you've got to concentrate on the few things that really matter.

That is why they keep it simple.

But if you forget everything else, 

please remember the slide, 

because you'll still can captured the essence of what you're going to say.

To make a good presentation that makes people remember of what you want to deliver to them.

the summary must repeat,

must come at the end of the pitch.

Which you have to keep it clear,

and keep it simple.

Remember, if they don't have confidence in you,

they certainly won't have confidence in your idea.

So make sure you keep it simple for your speech,

to gain the confidence,

for the audience,

and YOU.
