people are accepted, when they are free to express themselves and can
participate in making decisions that affect them, they enjoy greater
self-esteem, are more self-confident, and lose a sense of powerlessness
that’s always present in autocratic families.”
Dr Thomas Gordon, 2000
I have quoted this directly from the Effectiveness Training Institute of Australia website as a neat summary from the master as to why we should aim to create families that will provide the very best for our children. The ETIA training is not difficult - how to really listen (most people don't), how to be assertive (not aggressive, and most people aren't assertive either), and how to work out Win-Win agreements with children of all ages (and mostly we don't do that!)
And if you think it's just for parents, think again. Works great in the office or any workplace, or with friends, relatives... It's better human relations, and that means greater success and happiness in life. Worth it? Certainly is. It was Parent Effective Training (PET) that started me on my way, and the same with my children. Low cost, huge return. And you will find bits of it in all of our work. Best wishes to you.
