Throughout all my expeditions, the planning, and discipline instilled into me by my Royal Marines training has been invaluable. More than invaluable actually; it's saved my life (and those of others) on numerous occasions.

The EDI Process
The teaching process is designed to be simple and memorable under stressful circumstances. Every action is taught using a three‐step process:

- Imitate. You repeat what I've shown you on your own.
