I have designated places for all my stuff. Unless I’m interrupted by something important, I always put the object back in its right place. In my 20s I used to spend easily 30mins a day searching for stuff, but these days its a rarity.
It definitely helps. I still have a tendency to just put whatever I’m holding on the nearest available surface when I get distracted and completely forgetting about it though. But it helps as long as I’m not distracted at least!
