Get the Summary of Derick Howell's Eliminate Negative Thinking in 20 minutes. Please note: This is a summary & not the original book. Original book introduction: In fact, our brains are wired to look out for potential dangers. We remember negative events more vividly than positive ones. We instinctively look for negative things and imagine worst-case scenarios.

This instinct is helpful when you're lost in a jungle full of hungry predators.

But in our safe and comfortable lives, our negativity bias can get out of control. When you don't have to worry about being eaten by a tiger, your brain might start worrying about your future grandkids' careers or that awkward conversation that happened five years ago. If you don't make a conscious effort to manage your negative thoughts, you'll get lost in an endless loop of negativity - or, even worse, a downward spiral.
