I use to be my own worst enemy.  Use things, namely tools, not put them back where they belonged, had to hunt for them the next time I need them. With age comes experience, and sometimes the discipline to always put things back where they belong. Life it great. 

Can't say what changed... But it wasn't me. Now I still have to look for tools when I need to use them. They say OCD or simply didn't remember... 

Some things you're destined to live with...
