I tend to be hyper self-aware, as opposed to most of my fellow Americans. I believe this is what makes me a good driver while being assertive, efficient and courteous all at once. It also puts me in the 99th percentile of humanity when boarding and deplaning. To this end I tend to be a compulsive window shade manager as well.

Window shades open during takeoff, final approach, and landing without exception. Window shades open when the sun angle does not result in any passenger in the cabin from seeing the sun directly through my shade (not difficult to determine with a modicum of self-awareness). Window shade closed post-sunrise or pre-sunset during low sun angle hours when prior rule is nearly impossible to adhere to (unless on opposite side of plane). Shade at least mostly closed when over water or over cloud cover where there's objectively nothing to look at. Shade open when over terrain, thunderstorms, or any other time there's anything interesting below or adjacent, provided direct sunlight rule is not broken.

I don't prefer dark cabins during the daytime, so will usually keep my shades cracked a bit to let in some ambient light. None of this is worse than lights on in the cabin at nighttime. For whatever reason, I get this a lot on short hops on AS and WN such as OAK-RNO or PDX-SFO, etc. Though to their credit, they do often squeeze in a full service on 30-minute flights when AA flight attendants somehow "don't have time" from PHX-LAX.

wow, this list of rules sounds exhausting to keep track of. 😒
At the risk of getting sidetracked here, what all do you do that "also puts (you) in the 99th percentile of humanity when boarding and deplaning."

It's very simple. I don't approach the boarding area until my group is called, I leave space for wheelchairs and the elderly, I don't cut, I allow those with tight connections to deplane first, and help those in need of assistance getting luggage up and down. This all should be common courtesy but unfortunately is not the reality anymore.

Got it. I didn't realize you were just joking about being in the 99th percentile.

When I was growing up, I swear this was drilled into me to the point where I presumed it was a federal law. Yet now hardly anyone does it and I've only rarely heard in-flight announcements mentioning it.
