I am in need of some help/guidance in improving my powerpoint skills. I am currently working as a consultant and, as part of my role, I am required to prepare PPT slides. But because I am not very good at this, I don't feel confident in presenting my ideas to senior partners. This may sound bit OTT but whenever I see somebody presenting a good slide, instead of concentrating on the content, I start thinking about 'how they must have prepared this slide'.
Is there any book or any coaching available for preparing PPT? Please help.
