Sort of sounds like the old story The Happiness effect, about a doctor who works out an injection that keeps you happy and content no matter WHAT happens in your life. I'd also think of Gleemonex from Brain Candy, but that relies on HAVING a happy memory or though for it to lock you into.
Task, activity orientated ... the pickup lost a turn signal light after not being driven for some weeks. I discover that as I'm on my way to the store and sneak along the back way with no one behind me so that I don't need to worry about that back light. Then, it was off to the parts house. Back way ...
I should take the bulb out so that I find the right one. No problem, couple of screws, have a screwdriver behind the seat. Where are the screws on this thing!? Open the tailgate -- could those be the screws holding the taillight?? Only one way to find out.
It's cold and windy, I am miles from home. My nose is running. The whole taillight assembly comes out! It's in one part - I need a wrench! Gotta wrench - 3 bulbs, it must be the blackened one. How do I take it out? Got it!
Push things back in place, close tailgate, wipe my nose ... off I go.
A few minutes later, I'm back out there in the cold. New bulb fits! I manage not to drop any of the tiny screws. Everything lines up and signal works! I'm back in the cab legally heading home with the groceries. I felt so accomplished!
How many digitS' does it take to change a light bulb? Just one 😊.
