Having a structure and outline is great however if you are dead nervous even that might not help.
I remember in Uni during our public speaking classes the best two bits of advice were
1 Find a friendly soul and make eye contact during the talk
2 If you are struggling imagine the audience naked
Umpteen years later and applying those two has helped me.
Unfortunately, life is full of adult jerks to put it mildly.
I've heard the naked one before. Not sure I can bring myself to do that. You haven't seen some of these people! :) Thanks for the advice!
