I mean a big box. When you were in it the sides were nearly as tall as you were. And I remember two things vividly about the experience. Secondly, getting out could be hard and tricky because you had to tip the box over to get out and you could give yourself quite a ride in the process. Some of the most fun I have ever had in my work and in my life is when I am involved in doing creative things.
People throw aside convention and try things, experiment, push the limits and see what happens.
Nearly always Serendipity, unexpected surprise bought about by the experience. A second out of the box thing is to show people, by being a bit daft, that you don't take yourself too seriously. Eccentrics are always marvelous and interesting people to meet. We may not share their eccentrism but we are nevertheless affected by them and they breathe fresh air into our lives. As I say, we don't need to share their eccentrism but their willingness to break with conformity makes them healthier and more interesting people.
