Mahatma Gandhi

I did once seriously think of embracing the Christian faith. The gentle figure of Christ, so full of forgiveness that he taught his followers not to retaliate when abused or struck, but to turn the other cheek - I thought it was a beautiful example of the perfect man.

And I think that still is true of this business - which is basically research and development - that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.
