If you have a keyboard, you have the chance to speak to some people – the people who want to hear from you. It is possible, when the stars align, for that group to be a billion, or it might only be ten, but there is a number of people that you can engage with and if you change the culture then you change everything.
My argument for more than twenty years has been that we are each responsible for the culture where we are living, because we each have the ability to do something about it.
