Forever losing track of my things

Recently diagnosed with ASD. I am really bad at keeping track of my stuff. I am always losing things. I end up with two of something because I can't find the first one and then eventually find where I put it. It's so frustrating. I also don't get why people ask where is the last place you had it like if I knew that I could find it. I have a grounding tool that I really like but it's like it's vanished into thin air. Is this an autistic thing or just a me thing? Also any tips for stop losing things. routerlogin
