Your time is valuable and it’s important to make the most of every minute. Watching the clock, zoning out, stressing over all of the other things you could be doing -- nothing’s worse than a poorly planned meeting.

Take it from the pros: Limiting the amount of people in a meeting, appointing a leader and standing up are only a few ways top executives run successful meetings.

Say goodbye to those hour-long meetings or 30-slide PowerPoints. Turn your boring meetings into productivity powerhouses with these eight tips from industry leaders.

Dont plan a meeting in which two pizzas arent enough to feed everyone.

Jeff Bezos’ rule of thumb: “Don’t plan a meeting in which two pizzas aren’t enough to feed everyone.” Because the Amazon CEO conducts meetings that are a “free flow of ideas,” having too many people can make it hectic and confusing.

Having a limited number of people allows everyone to contribute ideas and keep the meeting on task, reports Inc.

Ditch the PowerPoint.

If you did your homework, you don’t need a slideshow to prove it. “I hate the way people use slideshows instead of thinking,” Steve Jobs told his biographer Walter Isaacson.

Jobs’s hypothesis was that if someone knows enough about a subject to discuss it, then they shouldn’t need a bunch of slides. At Apple, he banned the use of slideshows as a way to encourage employees “to debate passionately and think critically, all without leaning on technology.”

Put someone in charge.

Google CEO and co-founder Larry Page sent out a company-wide email that hit on the major points of how to run a productive meeting. His first point was to always choose one clearly appointed decision-maker for a meeting.

Meetings should be focused on decisions. If there's no decision-maker -- or no decision to be made -- the meeting shouldn't happen, his email explains.

Be in the know.

Mark Zuckerberg’s “ common sense strategy” for efficient meetings is preparing and sending materials in advance. This may sound like a no-brainer, but you’d be surprised how few people actually do this.

If meeting attendees get relevant materials beforehand, they’ll be in and out in no time. If everyone does their reading, there will be no need for repeatedly explaining items throughout the meeting, and you can jump straight to the point.

Dont be afraid to doodle.

It may sound counterproductive, but it works. Doodling can “clarify the brainstorming process,” Nike CEO Mark Parker says. Parker brings his notebook to every creative meeting to doodle new designs and jot down ideas.

It's not drawing nonsense shapes in your notebook as a means to ease boredom. This kind of creative doodling can get you to think about the task at hand and your creativity flowing.

Invite an outsider.

The CEO of Evernote, Phil Libin, invites a “high potential employee” that has nothing to do with a meeting’s topics to sit in and participate.

Libin recommends bringing in a department outsider as a means for employees to understand various parts of the company as well as ask questions and provide insight from a different viewpoint. In the end, it’s a win-win for everyone.

Stand up.

To avoid wasting precious time, have a " standing meeting" as a way to break up your day, avoid any distractions and make sure no one “nods off.” Standing will ensure your meeting is efficient and to the point.

Take it from Richard Branson, who says he thinks standing meetings are a “quicker way of getting down to business” and making a decision.

And if you want to take it a step further, Branson encourages walking meetings too (those are best for small groups).

Cut meetings in half.

Time is money, and if you’re wasting your time in an hour-long meeting that could have been 20 minutes, it’s time to reevaluate and restructure. Chop down those mindless minutes and cut your meeting times in half.

“If you plan a 15-minute meeting, you’ll find a way to get important stuff done,” entrepreneur, investor and author Gary Vaynerchuk says. “If you schedule a one-hour meeting, you’ll inevitably fill that time.”

Shorter meetings boost efficiency and get people focused on the matters at hand.
