My dumbest one was leaving the lens hood on and not checking it. Half my early moon shots had this weird dark blob on one side and I kept thinking my sensor was dirty. Spent a whole weekend reading cleaning guides and ordering swabs before my buddy pointed at the hood. Felt like a real genius. Now I flip the hood around and check the front glass before every session, takes ten seconds.

Sitting on things only works if the thing is actually gonna cool down on its own. Some stuff just grows teeth the longer it sits there, like a splinter you keep poking at instead of pulling out. Same reason I stopped doing the "wait a day" thing with texts from my sister, because by day two I was drafting a novel instead of just saying what happened. Fresh and small is real advice, the other version just works better for people whose heads don't spiral.
