Discipline's best friend

Mental toughness is discipline’s best friend. Rarely do you find one without the other. They’re so close they’re often mistaken for twins.

Maintaining discipline requires the resolve to say, “No.” Your heart and your stomach are going to fight to convince you to say, “Yes.” You can’t let them win.

Mental toughness is the superpower behind the disciplined man. It acts like a guardrail that keeps you on the right path. When weakness whispers in your ear and entices you stray, mental toughness kicks into action.
