My hope is that you do not have an inner voice that runs on a near constant track of "Not Good Enough". Sadly, I have this voice and she constantly rubs my nose in my failures and my perceived failures. She often compares my strengths against ridiculously high standards. In essence, she is TOXIC. Left to my own devices I often fall victim to her subtle and not so subtle messages, which are NEVER in my best interest.
But I can shut silence her and help redirect my thoughts and emotions in a positive direction, at least temporarily.
I have found a current favorite verse that I am working to memorize. I find that when I voice scripture, it silences the inner voice and give me a positive focus and outlook, as well as peace.
Jeremiah 29:11
For I know the plans I have for you, declares the Lord, plans for welfare and not for evil, to give you a hope and a future
With those words resonating in my mind and on my tongue, the critical inner voice is quieted.
