Discipline Over Motivation "Motivation is a feeling, and feelings are unreliable. They come when the sun is out and go when you’re tired or stressed. If you only work when you feel motivated, you’ll never build anything of substance. Discipline is the ability to do the work especially when you don’t feel like it. It’s a contract you sign with your future self. When the alarm goes off and your brain screams for more sleep, discipline is the voice that says, ‘We don’t do that.’ Build your life on discipline, and you’ll never be at the mercy of your moods."
