Being prepared for when things do not work out as planned is important. But planning for failure, is not planning to fail.
"Fate has ordained that the men who went to the moon to explore in peace will stay on the moon to rest in peace."
This is the opening of the speech President Nixon would have given the world, had the Apollo moon landings failed in 1969. At the time it was one of the most complex endeavours humans had ever attempted, with high risk, but an immense preparation for these risks, and the many measures to control them.
I hope 2015, brings you the best of outcomes, from the risks you choose to take, in full knowledge that they may not work out as perfectly as planned. But being prepared to minimise these bad events, will make the chance of many more good outcomes likely.
Its always good to shoot for the stars. But be ready and able to have the resources for a second and third Shot!
