The mind that stands still is the mind that grows roots. -- Jedi Maxim
Determining changes as appropriate, do not repeat former strategies to gain victory. This refers to victory in battle as well as confrontation. You can always improve on your former performance, even if the last attempt brought you absolute victory in that situation.
Victory and success can give one weaknesses, the ego is somthing a Jedi confronts and controls. Strategy can easily fall into a rut and become imperfect and eventually ineffective if you stop analyzing your actions. Even the greatest Jedi does not take their actions as being perfect, for in that action itsself would lie imperfection.
Whatever formations opponents may adopt, from the beginning you can adapt to them to attain victory. The Force flows, adapts to its environment. This must you do, and the Force will be with you.
‘Strong is the water that flows over each grain of sand, none may escape it's gentle touch.’ – from Oorin Krell's 'Campion's Song'
