Discipline

Discipline is not intensity. It is the boring repetition of a standard on the days no one is watching.

Built for the long grind

Motivation is weather. Discipline is climate. Anything you want to keep — a body, a business, a name — is maintained daily, not won once.

The standard doesn't move for your mood

Lower the bar once and you have taught yourself the bar is negotiable. Keep the standard fixed and let your mood argue with it, uselessly.
