Ah, technical presentations. For some, an opportunity to share. For others, nature’s cruelest mistake.1 And much like a total eclipse, technical presentations that are both well-prepared and well-executed are, sadly, a rare sight to behold. But, fear not! For those finding yourself in the latter camp, it doesn’t have to be this way. By applying some of these simple tricks, you can feel confident as a presenter, both leading up to and during your presentation.

 A reference to Homer Simpson, dubbed “Bottomless Pete” by Captain Horatio McCallister, in an episode of The Simpsons entitled, “New Kid on the Block”. From Wikipedia: After seeing a television advertisement about "The Frying Dutchman"'s all you can eat offer, Homer insists that Marge come dine with him, so he arranges for Laura to babysit Bart and Lisa in his and Marge's absence. After being served by the Sea Captain, Homer eats an excessive amount of food and is thrown out. He sues the restaurant for false advertising. Lionel Hutz is employed by him to represent him in court, and the Sea Captain and Homer eventually agree that Homer shall be displayed in the restaurant as "Bottomless Pete: Nature's Cruelest Mistake.”
 “Walkers” are presenters who tend to travel great distances on-stage, whether shuffling back-and-forth in one area or rocking side-to-side. These folks tend to move a lot on-stage because of a variety of reasons (e.g. nerves).
Minor one for new presenters, don't worry. A good friend told me before I went on stage MY first time.
"They will forgive you for being nervous as long as you know your material"
What I find helps me is to practice the content and the form. Memorizing a presentation Word for Word doesn't help me. But knowing the material and what I'm talking about does.
When you're up there, relax. Enjoy it. Have a little fun. Don't be afraid to smile.
And most of be yourself.
