## Details

## Overview

The "Decide Once" principle is one of the core Lazy Genius principles created by Kendra Adachi. It helps sidestep decision fatigue by clearly choosing what you'll do in a given situation—just one time.

## Core Concept

Identify areas where we're constantly using up brain power reinventing the wheel, deciding over and over again—then choose to simply decide once and stick with it.

## Connection to Time Management

By pre-deciding routine matters, you preserve mental energy and time for decisions that truly matter. The trickle-down effect of deciding once is significant—making these small decisions (once) will save you so much time and headache in the future.

## Practical Examples

- Wearing the same outfit style on specific days
- Having a standard gift for teacher appreciation
- Pre-planning weekly meals on rotation
- Establishing consistent morning routines
- Setting default times for specific types of activities

## Philosophy

The Lazy Genius approach is: "be a genius about the things that matter and lazy about the things that don't…to you." This principle works together with other concepts to create sustainable routines that reduce mental load and focus energy on what truly matters.
