Niche for my website

How does this sound for a niche for my website? “AcquireLight to manage your mind in order to reduce your negative self talk by 75% in 21 days so that your life and relationships feel easier, light, richer; for LDS wives.”
Any suggestions to tweak it?
Also, shall I put that on my home page?
I plan to offer short video messages, articles, quotations, questions to ask yourself and specific tools such as “Listen to, Walk with, Believe in”
