Front-load important decisions to morning hours when mental energy peaks. Schedule strategic thinking, hiring decisions, and creative work for when you're cognitively fresh, not after a day of meetings.
Batch routine decisions to preserve mental energy for what matters. Wear the same outfit daily, eat similar meals, create defaults for low-stakes choices. This isn't about rigidity—it's about resource allocation.
Create decision rules and systems that eliminate repeated deliberation. "I don't drink on weekdays" is easier to maintain than deciding each evening whether tonight is different. Pre-commitment eliminates the decision entirely.
Recognize when you're depleted. If you're irritable, impatient, or defaulting to whatever's easiest, your judgment is compromised. Delay important decisions until you've recovered. Simple awareness prevents costly mistakes made in a depleted state.
