You have only to rest in inaction and things will transform themselves. Smash your form and body, spit out hearing and eyesight, forget you are a thing among other things, and you may join in great unity with the deep and boundless.
Become one with yourself. When your body says something, listen to it. When your mind is burnt out, respect that. We can either work with or against ourselves; you choose which route you’d like to take.
When you need to, take a break. Really. Burning out is a thing, being overworked exists, and chronic fatigue happens. You must learn to listen to your mind and body; when they tell you you’ve had enough, that’s it; you’ve had enough. Working hard is important, however be careful not to overdo it; for the good of your own mind, body, and soul.
