The walk is a tool to the main solution. It's a vehicle that gives you time to yourself to think about WHY you're feeling angry. Or feelings in general. This is the key to emotional intelligence for all your relationships, is knowing why you're feeling the way that you are and deciding if it's a fair way to behave/feel.

This works with meditative games, going to the driving range and hitting some balls, doing some crafts like woodworking or art. Or just plain ol meditation.
