The Taylor Study Method has just posted an article I wrote on using gratitude to detox your brain. I pointed out that when you pay attention to negativity, you actually create toxins in your brain. This includes simply thinking negative thoughts. However, by cultivating an attitude of gratitude, you can starve all thinking that is negative, disordered or toxic. Just as fire can’t survive in an environment of water, so toxic thinking can’t survive in a neurological environment characterized by constant gratitude.
