In this audiobook, psychotherapist David Richo explores how we replay the past in our present-day relationships - and how we can free ourselves from this destructive pattern.

If there is one belief that has united the left and the right, psychologists and philosophers, ancient thinkers and modern ones, it is the tacit assumption that humans are bad. It's a notion that drives newspaper headlines and guides the laws that shape our lives. From Machiavelli to Hobbes, Freud to Pinker, the roots of this belief have sunk deep into Western thought. Human beings, we're taught, are by nature selfish and governed primarily by self-interest.

One of the very best scientific predictors for how any child turns out - in terms of happiness, academic success, leadership skills, and meaningful relationships - is whether at least one adult in their life has consistently shown up for them. In an age of scheduling demands and digital distractions, showing up for your child might sound like a tall order. But as best-selling authors Daniel Siegel and Tina Payne Bryson reassuringly explain, it doesn’t take a lot of time, energy, or money. Instead, showing up means offering a quality of presence.

Dr. William Glasser offers a new psychology that, if practiced, could reverse our widespread inability to get along with one another, an inability that is the source of almost all unhappiness. For progress in human relationships, he explains that we must give up the punishing, relationship-destroying external control psychology. For example, if you are in an unhappy relationship right now, he proposes that one or both of you could be using external control psychology on the other. He goes further. And suggests that misery is always related to a current unsatisfying relationship.

At least one-third of the people we know are introverts. They are the ones who prefer listening to speaking; who innovate and create but dislike self-promotion; who favor working on their own over working in teams. It is to introverts—Rosa Parks, Chopin, Dr. Seuss, Steve Wozniak—that we owe many of the great contributions to society.

The Bubble Theory is a deep, transformative exploration of the energetic dance between the masculine and feminine within oneself, and how mastering this inner polarity leads to true relational harmony. At the heart of this theory lies one central truth: when you learn to center yourself, you gain the power to shift fluidly into the energy that any moment, relationship, or interaction requires. Every interaction between two people can be seen as a "bubble", an energetic container seeking completion.

Full of illuminating stories and practical exercises, Debbie Ford shows us how to reconcile our darker impulses and find the gifts they offer.

Happily, the real source of great performance is no longer a mystery. Bringing together extensive scientific research, best-selling author Geoff Colvin shows where we go wrong and what actually makes world-class performers so remarkable.
