If more people in the world liked and valued themselves sufficiently I don't think we'd experience nearly as much hatred, violence and division. I think couples would be happier, relying less on the magical powers of each other to "fill the tanks." I think we'd all be more balanced and present, without the need for so much "mindfulness" training. I think we'd all get to the end of our lives with a greater sense of meaning and fulfillment, having loved ourselves and ultimately each other more fully.
So, if you landed in a family which didn't mirror you properly with wonder, acceptance and love, but instead either ignored, neglected or abused you, how do you develop self esteem? (Many people I've known think that if you weren't on the "right line" at the "right time" you're screwed)!
The contradicting good news is that self esteem is something that can be cultivated through practiced thought, action and attitude, rather than only possible through an ideal childhood. The wisest, most comprehensive article I've read about this issue was by Carthage Buckley, a performance coach and prolific writer whom I had the privilege of doing a podcast with last year about building a problem-solving mindset on my BlogTalk Radio show, The Couplespeak Relationship Forum. I've attached his article about raising self esteem through 7 exercises. Read it. Now. You'll be happy you did.
