'The reasonable man adapts himself to the world; the unreasonable man persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.' George Bernard Shaw

This is the first part of a three-part episode series where Colin explores the meaning of disagreeability in what he understands it to be. It would be nice for us to think that the people who change the world are always lovely, fluffy, cuddly people who are nice to everybody but I am sure a lot of the time that is not the case. It's just not possible to get things done.

In these three episodes, we're going to look at the possibility that we need to harness disagreeability, but I guess first we need to know what disagreeability is.
