If I’m remembering right, what Lenin wrote about beating liberalism basically amounted to aspiring to being the best, most respected and most reliable among your fellow workers while also not being shy about being a Communist and standing up to the bourgeoisie classes and their administrators.

Pragmatically gaining and spending social capital to win people over to the movement if you can, or at least making liberals look like shit and thereby encouraging people to be socialists and communists instead. Aspiring to being someone that your fellow workers can look to for support, either emotional or material.
