Nick Trenton's "Stop Overthinking" presents 23 techniques to manage anxiety and overthinking.

The book explores the interplay of genetics, environment, and personal thought patterns in contributing to anxiety. It offers practical strategies, including the "4 A's of Stress Management" (avoid, alter, accept, adapt), journaling techniques, and the 5-4-3-2-1 grounding method for immediate relief.

Furthermore, Trenton details relaxation methods, such as autogenic training, visualization, and cognitive behavioural therapy (CBT), to reframe negative thoughts. Finally, he emphasizes cultivating positive attitudes to foster long-term mental well-being.
