If your desire to improve your presentation skills, then the first step is this:
Resolve not to be your own worst enemy. Don’t tell yourself you can’t present, or that you’re not good in front of people or anything like that. Presenting is like learning any skill. You’ve got to master a few of the basic techniques, practice, get good feedback and you’ll be great.
Go through my tips. Find one that you really need to work on and do it over and over again.
Bottom line: If you can stand up straight, look people in the eye, speak in a big voice and smile, you can be a great presenter.
