We all know what is healthy to think and what is not, much like we know that eating an apple is better than gorging on donuts. But once we start thinking anxious thoughts, it is tough to move from disaster to reality. Our brain can ruin our day.

The road map to happiness can be found in Freeing Yourself from Anxiety. Unlike most guides, Dr. Tamar Chansky's book explains that the solution is not positive thinking but possible thinking. Armed with her strategies, listeners can achieve accurate perceptions of their lives that can liberate them from fear and perfectionism.

For the estimated 25 percent of Americans who have an anxiety problem, Freeing Yourself from Anxiety provides the step-by-step tools for living stress-free, without medications.

TAMAR E. CHANSKY, PHD is a clinical child psychologist, founder and director of the Children's Center for OCD and Anxiety, and the author of Freeing Your Child from Anxiety. She lives with her husband and two daughters in Philadelphia.
