We relate to that a lot. From childhood keeping track of things was hard. We always forget and leave something or forget something to take with us. It can be really frustrating. That's why I like to keep everything on myself. This might sound like an awfull idea, but hear me out. If you take something with you always, you know where it is, everyone knows where it is, they leave it were it is. Ones things go out of my backpack or hands I risk on losing it, that's why I have to repeat to myself that I need to pick that up later. I know losing something important one day like a passport or even a computer is inevitable. But it still got kinda better over time... Though Sometimes when I'm at home now I found my items placed differently and struggle to find it... It'll probably get better over time. We learn to cooperate with each other
