I think that the main message (for me at least) of this lecture was to start doing and creating together with the others, and the more the merrier. We just have to roll up our sleeves and start doing our thing. And it is important to involve non-designers to work together with designers and other professionals to create better life for us all. We have all the time more and more tools to use and people who are interested to get involved. And it is important to share our ideas with the others.
