The rule of thirds is that when you're chasing a dream or doing anything hard, you're supposed to feel good a third of the time, OK a third of the time and crappy a third of the time. If you're within this ratio, then the bad days aren't bad. They just mean you're chasing a dream.

Most people overestimate what they can do in one year and underestimate what they can do in ten years. But the deeper error is that they plan in one-year chunks at all — the unit of compounding is decades, not quarters.
Jeff Bezos — Amazon Shareholder Letter
Everything had fallen away from him during those years: money, power, fame; nothing was certain for him anymore: not life, not health, not happiness; all had been called into question for him: vanity, ambition, relationships. Everything was reduced to bare existence. Burnt through with pain, everything that was not essential was melted down — the human being reduced to what he was in the last analysis: either a member of the masses, therefore no one real, so really no one — the anonymous one, a nameless thing (!), that "he" had now become, just a prisoner number; or else he melted right down to his essential self.
