High self esteem matters because how you function as a person is determined by your self esteem. If you have low self esteem it affects every part of your life. You will not feel good about yourself and have trouble valuing yourself. You will not believe that good things are possible for you. Being a victim of domestic violence often affects your self esteem and you often think bad about yourself. Expecting bad things to happen for you. Also abusers usually have low self esteem and need to work on their issues so that they can do better in life and not abuse others.
When you have high self esteem you treat others in the following way
Treat everyone as equal
Work on improving themselves
Admit when they are wrong
They love others from choice
They have a secure base to operate from
They have a can do attitude to life
Here is a book I have found that works on these issues. The Self Esteem Workbook by Glenn R Schiraldi. PhD
There is a book called the self esteem workbook and you do it at home in your own time and work on improving your self esteem.
I would recommend it to anyone who has been a victim of abuse and Domestic Violence or is an abuser. I am currently doing it myself.
Moral Work on improving your self esteem so that you can have a much happier life!
