The Element of Surprise.

Niccolo Machiavelli once said 'surprise is the most essential factor of victory...nothing makes a leader greater than the capacity to guess the design of the enemy'.
There is a certain beauty surprise injects into life. We throw surpise parties, give surprising gifts and plan events and take steps of all sorts that are a surprise to people around us. Surprise in itself is an interesting occurence. The expectation it erupts and the suddenness it springs up puts a certain flavour to the moment. The art of surprising is a useful one. It's the power behind laying an ambush for an adversary. It's  part of the skill that makes hunters go home with game and survive out in the wild.
The element of surprise is also a useful one in warfare and other fields of life.
In warfare the element of surprise puts the 'warrior' who employs it at an advantage. History attests to this fact.
'Surprise, very frequently has ended a war with a single stroke'- Clausewitz
