Anxiety is a tough nut to crack. Somedays, you’ll feel like that squirrel from the Ice Age movie—trying to break that nut on any surface you can find but getting nowhere fast. You’ll give up exhausted after hours of wrestling with the nut. And the nut will win. Then on other days, you’ll find cracking the anxiety nut is easy. You’ll get your anxiety under control in no time at all. And you’ll feel triumphant.
