What loss is there in dignity, what worry is there of failure?
Battles are not won by strength alone!
To overcome the intelligent by folly is contrary to the natural order of things; to overcome the foolish by intelligence is in accord with the natural order. To overcome the intelligent by intelligence, however, is a matter of opportunity.
There is no greater weapon than a prepared mind.
Do the unexpected, attack the unprepared.
Detach from emotions and desires; get rid of any fixations.
