Victory is within easy reach, but we mustn't let our guard down.
Tips
history
Traces to a commentary in 《后汉书·公孙瓒传》 citing 《九州春秋》： 始天下兵起，我谓唾掌而决 - 'when the empire first rose in arms, I thought victory could be decided by spitting in one's palm.'
memory
Picture the speaker spitting on his hand to get a good grip - victory is so close you barely need to lift a finger.
