Identifying the Root Cause of Limiting Beliefs

I hear a lot in personal development work with limiting beliefs and obviously you mentioned before that these can be created in the womb from the ages of one to seven. So how important do you think it is for someone to identify the root cause of a limiting belief? Or is it more important to just understand what the limiting belief is and then try to override that, like you said, with positive experiences? Because I myself have found it really challenging, like whether it's a bad memory, whether I'm not as good at regression as I thought I was. And so we all had those moments that were like the pinnacle moment, the epitome of when that limiting belief was formed.
