Stroll to the Watering Hole
Once cognitions (thoughts/ideas) have been assessed and altered it's time to decide how that would change behaviors and pursue those changes.
Homework outside of sessions moves you from cognitions (thoughts) to trying things for real (behaviors). You don't truly know what works until you find out if you can get a drink or a shower in a world of limitations, hungry lions, mocking hyenas, and many other challenges life presents. Evaluation and alteration continue until you are no longer thirsty and smell clean.
