Hi, I need a little clarification on when to use side a or side b for the belief paraliminal.

Say that I want to create the belief that people like me. Would I first need to use side a to remove the current belief that 'people don't like me', and then later use side b to install the belief: 'people like me'? Or could I just use only side b to create that belief, and it would nullify the limiting belief? Thanks.
