From an organisational point of view, it's better to focus on doing a small number of things right, than a large number of things wrong.

In September 2009, I held a Guinness World Record attempt for the Largest Robot Dance.  About 350 people attended.  In September 2010, I held the Robots Are Coming robotics art exhibition in the middle of Wynyard Park.  Over 100,000 people saw the exhibition during the course of that week.

Both these events were followed by 3-day conferences that I organised and ran.  That was tiring.

In October 2010, I was exhausted, and I decided I would not hold an event like that again.  I decided Robogals Global would focus on running robotics workshops very well and to only run large projects that directly achieved our aim of getting girls interested in engineering.  Instead, we would encourage Robogals chapters to hold community events like the Robot Dance and Robotic Art Exhibition if they were interested in doing so in their communities.

By doing that, Robogals is able to develop up a core number of programs, while Robogals chapters around the world are given the freedom and support to do amazing things around the world, such as Robogals Caltech consulting with Disney Pixar on a movie about "Tinkerbell:  the engineer", tea parties held by Robogals Western Australia, Robogals Girls in Robotics Days by Robogals University of Queensland, and Robogals London's collaborations with the London Science Museum holding themed robotics holiday workshops.

Focus on getting a small number of things right, and it will enable you to grow into doing a larger number of things right.
