It’s essentially a Marcus Aurelius quote from Meditations written around 170 AD. “If thou art pained by any external thing, it is not this thing that disturbs thee, but thy own judgment about it. And it is in thy power to wipe out this judgment now.”

Agreed. These words shouldn’t be attributed to Holiday. While I like his work, he isn’t bringing new ideas to the table. Just rewriting what’s already been written for our time (which is valuable in its own way).
