I had to do a presentation today at work in front of a relatively large group (~50). It was received relatively well, but this is one area I would really like to improve on. No matter what you do, one is never prepared for the anxiety and excitement for public speeches. Couple of notes that helped me
1) Prepare for the meeting. Unless you are a Bill Clinton, you need to have some notes :).
2) Run a practise session. Helps to review the first step and also time your presentation.
3) Don’t go into details!!!
4) And speak LOUDLY and c-l-e-a-r-l-y. The first part is an issue for me :).
