We all like to leave our mark. Some wait for the very end and summarise their life in stone, suspended over a hole in the ground in which our final remains become the excrement of a lesser life. Others will scratch their philosophy on a wall, or scribble, in passing, a small note to the next passer by. Its a gesture, lke a nod of the head or a print on a T-shirt. The words label us as part of the continuum and we have made our mark, as brief and inconclusive as it may seem. Tomorrow it will fade in the light of the Sun or loose its place in the context of a new generation. But if one person lives their life by this, then that may well be enough. Someone will read it and possibly stop to think: 'Is that worth knowing?' Then we know we have begun to change the world.
