Law 48 of 48 laws of power by Robert Greene says assume formlessness.
By taking a shape, by having a visible plan, you open yourself to attack. Instead of taking a form for your enemy to grasp, keep yourself adaptable and on the move. Accept the fact that nothing is certain and no law is fixed. The best way to protect yourself is to be as fluid and formless as water, never bet on stability or lasting order. Everything changes.
Very, very good suggestion for survival in most arenas. power or not!
