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. We all have a tendency to transfer potent feelings, needs, expectations, and beliefs from childhood or from former relationships onto the people in our daily lives, whether they are our intimate partners, friends, or acquaintances.

In order to improve closeness and intimacy in all relationships, it is important to first understand the clear parallels between adult behavior and childhood experiences.

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 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.

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.

Human beings, we're taught, are by nature selfish and governed primarily by self-interest.

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.

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.

Debbie Ford explains that the dark side of our personality should not be hidden. By denying our dark side, we reject aspects of our true natures rather than giving ourselves the freedom to live authentically. Here she shows that it is possible to acknowledge and accept our so-called weaknesses, proving that these qualities may be hidden strengths. Full of illuminating stories and practical exercises, Debbie Ford shows us how to reconcile our darker impulses and find the gifts they offer.

Over time, these persistent demands leave us burnt out because our nervous system is stuck in survival mode. In this mode, we have reduced capacity for rational thinking and less capacity to care. Dr. Claire Plumbly draws on polyvagal theory and her professional insights as a trauma therapist working with clients experiencing anxiety, trauma and burnout to give you tools to thrive amidst the challenges of modern life, at work, at home.
