Individualism is deceitful and insidious; it treacherously pulls one down. And it is always easier to go down than up. 

This makes individualism especially dangerous. In order to uproot the survivals of the past and foster in ourselves the moral qualities of a true revolutionary we must study, educate ourselves, transform ourselves in order to move on indefatigably. 

If one does not strive to make progress one will inevitably stop and fall behind. And if one stops and falls behind, the developing society will cast them aside. 

If one possesses the moral qualities of a revolutionary, they will not become frightened, lose their head or retreat before difficulties and defeats. One will, without hesitation, sacrifice their personal interests for the sake of the common interests of the party, the revolution, the working class, the nation and the whole of humanity.
