Mike Monteiro - 13 ways to screw up a presentation.

• You're not the client's friend, they have a need for you to solve don't try to be more than that. 
• Not getting off your ass and making it obvious who is giving the presentation. 
• Starting with an apology, people will start to trust you less if they think you've done something wrong/ less than you should have. 
• Not setting the stage properly, let them know why you want/ need them there.
• Giving the real estate tour.
• Taking notes.
• Reading a script, show you know it and believe in what you're presenting by not needing notes. 
• Getting defensive, you are not your work and your work is not you.
• Mentioning typefaces, clients dont care
• Talking about how hard you worked, if you did it right work should look effortless even if it wasn't.
• Reacting to questions as change requests, back your design up and say why you have made certain design decisions.
• Not guiding the feedback, tell them what sort of feedback you want.
