Relying on Willpower Instead of Building Systems

Willpower is a depletable resource. It works great at 8 AM and fails reliably at 8 PM. If your productivity depends on being disciplined every single day, it will fail — not because you are weak, but because that's how willpower works.

Build systems that make the right action the easy action. Put the book on the pillow. Block distracting sites. Prepare meals on Sunday. When the system does the heavy lifting, willpower becomes a backup, not the engine.
