Quick answer: Keep a permanent kit built from the Ten Essentials: headlamp with spare batteries, compact first aid, knife and repair tape, lighter and fire starter, emergency blanket, sunscreen and sunglasses, water treatment, and a small bag of long-life snacks. Add navigation and clothing per trip. REI lists these ten systems as what to carry on every outing.
The difference between a prepared hiker and a forgetful one is usually what lives in the pack between trips.
This guide splits the Ten Essentials into what stays and what you add each time.

Honest Limits
The Ten Essentials are a framework. Conditions, season and group change what you carry, and a permanent kit does not replace trip planning.
