I haven’t worked much with Limit Destroyer, but the following are direct quotes from the sales page:
“With each loop, Limit Destroyer will drill deeper and deeper into your subconscious, removing the fears and limits that hold you back from greatness.”
“You could potentially experience incredible boosts of confidence, bravery and fearlessness in just a few days.”
“permanently remove ANY issues that are limiting your personal, professional, or romantic growth”
“provide you with the mental tools and fortitude to overcome them.”
“you can use it to destroy wealth limits, sexual hangups, social problems (such as anxiety)”
So, it seems that this is a wise choice for you to include. LD alone, added to your desire to grow in this area, is already a formidable resource.
Another module I’d recommend for working with your internal monologue and perceptions:
Inner Voice
"An inner voice that does not put us down, but lifts us ever upwards. This module will change your whole mental landscape, transforming it into a positive space where good things happen."
And for this issue:
A good module is:
Natural Winner
From the description:
"You will also let go of negativity, and you will start feeling as if success is simply your destiny and is inevitable."
Combined with New Beginnings, could be a powerful combination.
"designed to dig to the deepest, darkest corners of your psyche, in order to deal with your innermost secrets and fears that you never even knew existed"
I like LION IV and Harmonic Singularity too.
