The mind wants action all the time. But there is none. Reality consists of Being, not doing. Reality requires non-action, the effortlessness in all things. Nothing exists for long.
There aren't any explanations for whats going on. Society is set up to feed the mind. Motivational speakers keep things alive that are supposed to die. You are being motivated to hold on. But you can't hold on, it has to slip away. You are beating yourself up because you can't get yourself to do things. You don't need motivation, all you need is death, let go, and what arises is who you truly are. Doing nothing is where its at.
