Without armed struggle neither the proletariat, nor the people, nor the Communist Party would have any standing at all in China and it would be impossible for the revolution to triumph. In these years [the eighteen years since the founding of the Party] the development, consolidation and bolshevization of our Party have proceeded in the midst of revolutionary wars; without armed struggle the Communist Party would assuredly not be what it is today. Comrades throughout the Party must never forget this experience for which we have paid in blood.
Mao ZedongWhat is work? Work is struggle. There are difficulties and problems in those places for us to overcome and solve. We go there to work and struggle to overcome these difficulties. A good comrade is one who is more eager to go where the difficulties are greater.
Mao ZedongA strategic plan based on the over-all situation of both belligerents is ... more stable, but it too is applicable only in a given strategic stage and has to be changed when the war moves towards a new stage. ... [Conversely, tactical plans may] ... have to be changed several times a day.
