That's advice that will get you a burnout. Hope, especially when sought for with the purpose of maintaining high levels of stress, will break you when it becomes implausible.
It is a promise that can become false, and once your body knows you're willing to lie to trick it into greater productivity, it'll just stop listening to you.

It's solidarity networks, resource pooling, leaning on friends and comrades and letting them lean on you, and forming collectives.
It's unionizing, demonstration, occupation, and revolution.
