I’ve given 379 talks. This is something I wish I would have known years ago...

...how to warm up a room. 

Your talk begins long before you open your mouth. 

Talking to a room of 50 people or less? If you have time, shake every hand in the room before you begin your presentation. 

Speaking at a conference in front of thousands of people? Go to a bunch of sections in the room and say hello to people. 

Listen, learn, laugh...

...this will radically help you when you're on stage. 

Warm up that room!
