This is usually as much about boundaries as anything else. When we have self-respect we are able to say "no" without feeling guilty. We are able to ask for help when we need it. We are able to understand and use our strengths for the best outcomes. We are able to magnetise in situations that will help us.
Why and how does this happen?
When we have self-respect we intuitively know what is right and wrong, what will 'work' and what won't. There are few doubts about how to move forward in life and this gives signals to those around who in turn honour that 'message'. We appear 'strong' and others respect this.
In what areas of your life are you lacking in self-respect? This is a question we should all ask ourselves on occassion.
