The more you practice, the more you rehearse, the more you get on top of your story. And the more comfortable you get with your material, the more confident you get in delivering it. Confidence goes beyond getting rid of fear of public speaking, confidence enters chart design and story telling as well.
- The confidence to get rid of "business school"-style structuring frameworks: let's talk about the market, let's talk about the competition, let's talk about the distinctiveness, etc. and only spend time on those issues that really matter for your particular story, in the order that best fit your specific situation
- The confidence to use personal stories and case examples to illustrate your point
- The confidence to make your charts more minimalist and more abstract
- The confidence to insert blank/black/white slides inside your presentation to have the audience just focus on you
It is a bit like the abstract painters of the last century: having the confidence to communicate emotions and ideas without relying on realistic techniques. For example Piet Mondriaan's Broadway Boogie Woogie painted in 1942-1943.
The pulse of a Jazz beat, and the energy of the New York traffic squeezing its way through the city's grid all captured in one painting without showing Jazz bars, Times Square neons, and/or New York traffic jams.
