# Do this calculation every time you speak in public

Whenever you have a speech or presentation to deliver, there’s a calculation that you should always do beforehand. Multiply the time you have to speak by the number of people whom you anticipate will be in the audience. The result is the true amount of your speaking time. Because, however long you speak, each person in the audience is spending that much time with you.

Thus, for example, if you are going to speak for 45 minutes to 20 people, the calculation would be: 45 x 20 = 900 minutes or 15 hours of total time. If you are going to speak for 30 minutes to 50 people, the calculation would be: 30 x 50 = 1,500 minutes or 25 hours of total time.

In 2016, I gave a 1-hour workshop to 1,000 people at the Toastmasters International Convention in Washington. So that was 1,000 hours of total time! For a single person, it would be 25 weeks of work, assuming a 40-work week.

Knowing the true amount of your speaking time should change your perspective whenever you have a speech or presentation. People will never get that time back and so you have to make whatever you say worth their while.

I first got in touch with John while preparing to speak at TED Global about my work on ProtonMail. John helped me to sharpen the presentation and get on point faster, making the talk more focused and impactful. My speech was very well received, has since reached almost 1.8 million people and was successful in explaining a complex subject (email encryption) to a general audience.

Andy Yen

CEO, Proton Technologies

John gave the opening keynote on the second day of our unit’s recent offsite in Geneva, addressing an audience of 100+ attendees with a wealth of tips and techniques to deliver powerful, memorable presentations. I applied some of these techniques the very next week in an internal presentation, and I’ve been asked to give that presentation again to senior management, which has NEVER happened before. John is one of the greatest speakers I know and I can recommend his services without reservation.

After a morning of team building activities using improvisation as the conduit, John came on stage to close the staff event which was organised in Chamonix, France. His energy and presence were immediately felt by all the members of staff. The work put into the preparation of his speech was evident and by sharing some his own stories, he was able to conduct a closing inspirational speech which was relevant, powerful and impactful for all at IRU. The whole team left feeling engaged and motivated to tackle the 2019 objectives ahead. Thank you, John.

Secretary General, World Road Transport Organization

I was expecting a few speaking tips and tricks and a few fun exercises, but you went above and beyond – and sideways. You taught me to stand tall. You taught me to anchor myself. You taught me to breathe. You taught me to open up. You taught me to look people in the eye. You taught me to tell the truth. You taught me to walk a mile in someone else’s shoes. I got more than I bargained for in the best possible way.

John gave a brilliant presentation on public speaking during the UN EMERGE programme in Geneva (a two days workshop on leadership development for a group of female staff members working in the UN organizations in Geneva). His talk was inspirational and practical, thanks to the many techniques and tips he shared with the audience. His teaching can dramatically change our public speaking performance and enable us as presenters to have a real and powerful impact. Thank you, John, for your great contribution!

Sara Canna

HR Specialist, World Health Organization

John is a genuine communication innovator. His seminars on gamification of public speaking learning and his interactive Rhetoric game at our conference set the tone for change and improvement in our organisation. The quality of his input, the impact he made with his audience and his effortlessly engaging style made it easy to get on board with his core messages and won over some delegates who were extremely skeptical as to the efficacy of games for learning. I simply cannot recommend him highly enough.

John joined our Global Sales Meeting in Segovia, Spain and we all participated in his "Improv(e) your Work!" session. I say “all” because it really was all interactive, participatory, learning and enjoyable. The session surprised everybody and was a fresh-air activity that brought a lot of self-reflection and insights to improve trust and confidence in each other inside our team. It´s all about communication and a good manner of speaking!"

Everyone enjoyed the good mix of listening to your speech, co-developing a concrete take-away and the personal learning experience. We all feel more devoted to the task ahead, more able to succeed and an elevated team spirit. Delivering this in a short time, both in session and in preparation, is outstanding!

Be BOLD. Those two words got stuck in my head and in the heads of all those ADP leaders and associates that had the privilege to see John on stage. He was our keynote speaker at our annual convention in Barcelona, and his message still remains! John puts his heart in every word. Few speakers are so credible, humble and yet super strong with large audiences!
