How to Make Your Brain Your Best Friend

by Rachel Barr

Always trying to mend itself, and always trying to protect you, it’s in a constant state of flux ― adapting, reconfiguring, finding new pathways . . . And it has an astonishing capacity for recovery.

Only it doesn’t always get it right.

Rachel Barr struggled through years of devastating loss, heartache, and uncertainty until neuroscience gave her the first spark of self-belief she had felt in her adult life ― and proof that, because of the brain’s near-infinite potential for neuroplastic change, it’s never too late to carve out neural pathways to form new habits, new skills, and new ways of thinking.

Whether you want to nerd-out on Neuroscientific acronyms, finally understand what’s going on in your head, or take refuge in a book that’s like a warm hug for your mind, How to Make Your Brain Your Best Friend is a delight-filled, evidence-based guide to taking better care of your brain ― so it, in turn, will take better care of you.
