Some of the most important things you can do: — Know your equipment, if you know the material backwards and forwards will be safer and more comfortable – Practice, practice, practice – Take every opportunity to speak before others can. – A video tape, you probably are not doing as bad as you think! – Join Toastmasters – A nonprofit organization profit, with 250,000 members worldwide.
