I think any situation in which you have to work with a diverse group of people will be a really valuable experience, especially for working in the real world. In life you have to figure out how to motivate people, how to help others to open their minds to new ideas, thats a big part of what being a leader is about (not just delegating and having power).
One of the most important aspects of this process is staying positive and offering constructive criticism, rather than shutting down ideas or adamantly enforcing a certain attitude or lifestyle.
For the toolkit, I would make the connection between the solar decathlon and sustainability decathlon more clear and recruit more people from the solar decathlon team.
Even though I was in high school a mere two years ago, I don?t think an environment club existed on my campus. The force at which the eco-movement has spread is mind boggling and to be witness to such devotion to the environment at a high school level is very impressive, if not a little humbling.
This competition has given these students the opportunity to experience something new that they probably would not have experienced at their school and hopefully has had a significant effect on their lives.
