To attain this super-power one needs to learn how to put yourself in peripheral vision(looking at multiple things at any given time). Now close your eyes and see the difference. This is also a powernap technique. Pls refer my article on this - https://www.linkedin.com/pulse/state-our-eyes-nitin-sareen/
Would strongly recommend POMODORO technique for all computer professionals. Everything else is just a growing side business due to the lack of knowledge of our own physiology.
Use pantheon.io hosting for a wordpress or drupal hosting, its free if you don't associate a custom domain. In a headless formulation, you can use them free forever! Plus its darn easy to implement CRUD on any of them.
Fork a svelte frontend and host it over services like netlify or vercel which too ofcourse are free!
Have you given headless CMS a look? I'm specifically referring to Drupal hosted on Pantheon. This is a completely free backend that can fulfill your requirement list. On top of it, use a JS frontend using Svelte/Vue/React and use again a free hosting like Netlify/Vercel. I've built multiple MVP's with this approach and found it to be quiet convenient.
Put your eyes in peripheral vision mode (looking at multiple objects at the same time). This helps you de-focus and helps de-stress your eyes and facial muscles. Some what magically your brain goes into relaxation mode which eventually helps in deep and fast sleep.
Have been doing this from about 8 months, never failed me once.
