Here's what I have in my intro Marxist-Leninist reading list, section 9: Party Work and section 10: Self-Conduct:
Section 9: Party Work [5hr 12 min]
You can't build communism by reading it into existence. Roll up your sleeves, and get to work.
- J. V. Stalin's The Foundations of Leninism
[2 hr 2 min]
Marxism-Leninism is the living and evolving Marxism that has tested theory to practice for over a century.
- V. I. Lenin's What is to be Done? (Abridged)
[70 min]
The fundamental tasks of the revolutionary party.
- Liu Shaoqi's How to be a Good Communist | Audiobook
[~1 hour]
If we are to be successful, we must work to better ourselves, and do good party work.
- Liu Shaoqi's On the Party: Concerning the Mass Line of Our Party
[~30 min]
The mass line is the fundamental tool of maintaining a direct link between the working class and the vanguard, without falling into tailism or commandism.
- Liu Shaoqi's On the Party: Democratic Centralism Within the Party
[~30 min]
Democratic centralism turns an amorphous but radicalized working class into a solidified force to overwhelm its enemies. It takes the greatest strength of the proletariat, its mass, and aligns it in a unified direction.
Section 10: Self-Conduct [2 hr 39 min]
We cannot be dogmatic, or let the perfect socialism in our heads be the enemy of socialism in the real world.
- V. I. Lenin's "Left-Wing" Communism | Audiobook
[1 hr 47 min]
As organizers, we must do our best to engage where the working class is at, and not let the perfect socialism in our heads be the enemy of our own practice.
[17 min]
Marxism in western countries is often clouded by those who seem to only support socialism that failed, the "pure" socialist movements unsullied by the very real struggles involved in building socialism over a lengthy period of time. This perfect vision of socialism in our heads becomes not just the enemy of our practice, but also that of socialists in the global south that fought and died for a better world.
- Zhou Enlai's Guidelines for Myself
[1 min]
Simple and straightforward virtues for any good cadre.
- Xi Jinping's Water Droplets Drilling Through Rock
[4 min]
Tenacity is what creates valleys and shifts mountains. Through our connected struggle, even if the odds seem overwhelming, we all contribute to bringing about a better world.
- Ho Chi Minh's On Revolutionary Morality
[~30 min]
We must combat the notion of putting self-interest above that of our collective struggle. It is through collaboration that we emancipate all, not just ourselves.
Obviously you can skip Lenin's What is to be Done? as you've already read it. Liu Shaoqi's work in particular is helpful for understanding how the CPC organizes. In addition, Gramsci's The Communist Party is quite good, as is Jo Freeman's The Tyranny of Structurelessness.
