Like you already found with your blog and youtube channel, it can be difficult to find something set and forget. You don't have much chance of that channel being monitised, as its a low value content. Maybe if there was free transition, and effects and other green screen relaxing elements, you will have a better chance. But yes, if there was an easy set and forget daily, no one would share it with anyone, until you find one assume they don't exist. The marketing experts say it takes 30 attempts to find 1 success. So keep doing what your doing, just do it better, and scale up your effort and input.
