mRNA could be said to be in the trough of disillusionment -- didn't prevent COVID as initially promised, and has problems like causing heart damage in rare cases.
This disillusionment is evidenced by lower proportion of people seeking to take such injections now.
When stuck I do what I call "prepping". Don't try to do the task, just prep for it -- clean the room, the desk, close distracting websites, gather the materials.
It's lowering the activation energy so the reaction can happen more easily.
When I was younger, dark room, dark screen was fine. Gets harder to focus as you age. Bright screen and room cause smaller pupils and therefore easier focusing like a pinhole camera.
