The Best tips to start a presentation in good way

Tell a motivational story.

Story telling is the most powerful and consistently successful tool" As humans, we are hard-wired to enjoy and learn from stories. From bedtime stories and campfires, to Broadway theaters and boardrooms — heroes, villains, conflict, plots, dialogue, and lessons learned draw us in, remind us of our own lives, and hold our attention.
The story can be about you personally, which tells the audience first-hand why you are invested in and passionate about the topic. Or you can tell a story about another person who the audience can learn from.
Another option: tell a fable, wisdom tale, historic event. The idea is, start with a brief 60 to 90 second narrative that launches your speech and captivates your listeners, and make sure the story encapsulates the key point of your message.
you consider these questions as you craft your version of  "Once upon a time": What challenges have you (or another) faced in relation to your topic? How did you (or another) overcome them? Who or what helped you or harmed you? What lessons were learned? What do you want your audience to gain, feel, or do as a result of the story?

Ask a stylistic thought-excited question.

As Shakespeare wrote in "The Merchant of Venice," "If you prick us, do we not bleed? If you tickle us, do we not laugh? If you poison us, do we not die? And if you wrong us, shall we not revenge?"
"As a speaker, you ask stylistic questions for convincing effect; you do not expect the audience to answer aloud, rather silently to themselves". When crafted and delivered well, stylistic questions influence an audience to believe in the position of the speaker. What do you want your audience to say yes or No to?"
In addition to yes or no questions, you can also increase curiosity and motivate your audience to think about the answer.

State a shocking statistic or headline.

The vice president of sales for Americas leading healthcare IT company successfully sells software solutions to hospitals by starting her presentations with the following:
"According to a new study in the Journal of Patient Safety, medical errors leading to patient death are much higher than previously thought. Preventable adverse events, known as PAEs, cause up to 400,000 deaths per year for patients who seek care at a hospital. That means medical errors are the third leading cause of death behind heart disease and cancer. Our vision is to create a world free of medical errors, and we need your help."

"The statistic, bold claim, or headline needs to be directly related to the main purpose of your presentation. "Its impact ideally persuades the audience to listen and respond positively to your recommendation and next steps."

Use a powerful quote.

Employ the wise words of a well-known person because the name allows you to tap into his or her credibility, like ability, and notoriety. The quote must have meaning and relevance to the audience.
Imagine you are urging a group to reach consensus, or giving a talk on conflict management. You could open with: "Mark Twain once said, If two people agree on everything, one of them is unnecessary. Even though some of us disagree on the xyz issue, each of us is necessary in the reaching a resolution."

Show a gripping photo

A picture is worth a thousand words — "maybe even more, Use photos instead of text, when possible. A quality photo ads impressive appeal, increases comprehension, engages the audiences imagination, and makes the message more memorable.Example of an effective use of an image:
The president of an electronics equipment company needed his managers to cut costs. Rather than showing simple charts, graphs, and spreadsheets, he opened the meeting by asking, "What sank the Titanic?" When everyone in group replied, "an iceberg," he displayed a beautiful high-definition image of an iceberg on the screen: the tip of the iceberg was clearly visible above the water; the much larger portion was dimly visible below the surface of the water.
"The same thing is about to happen to our company," he continued. "Hidden costs — the dangers beneath the surface — are about to sink this company. I need your help." This visual metaphor spawned a creative, productive brainstorming session that inspired every business unit manager to diligently hunt for what they labelled the "icebergs. The result was saving millions and ultimately the company.

Use a prop or creative visual aid

"A prop is a magnetic tool that hooks your audience and keeps them watching — or listening A visual aid can also help emphasize a point.
Example: A sales VP at a large insurance company, who happens to be an avid tennis player. She says he wanted to kick off his annual meeting with a bang — so he "brilliantly used his tennis racket to emphasize acting the competition, allying together as a team, and winning a grand slam through great customer service." Year after year, other speakers were compared to this leaders creative ability to present a motivational message.
"Think about how you could use items like a big wall clock, a colorful gift bag, juggling balls, a deck of cards, a bunch of carrots, or another prop, to introduce your topic, captivate the audience, inject humor and drive home your message."

Play a short video

Imagine kicking off a product management meeting with a video of compelling customer testimonials, or opening a fund raising event for endangered species by showing an Amur Leopard playing with her cubs in the wild.
"Videos evoke emotional responses,Unlike text and bullet points on a slide, you can employ people, pictures, and sound to reel in the audience, add drama, and communicate the idea of your message quickly." As Walt Disney said, "I would rather entertain and hope that people learned something than educate people and hope they were entertained."
