mind loss

I have to be the dumbest twit on this planet. I have this tendency to keep important things so safely that i myself forget where i keep them and then keep searching for them like crazy. Obviously this searching happens when i am in dire need of these things(most frequently documents) and when i cannot find them i have to do procedures to get copies and duplicates which is even more irritating sometimes impossible.
the first question people ask is how did you lose these documents? there are things in this world that you just lose and there is no explanation for it. explanations are possible only when u have been in unfortunate (maybe funny) accidents of sorts. but sadly, this is never the case with me. i simply forget where i keep my important sheets of paper even though i know they are supremely important.
i wish life were like a treasure hunt game with clues to what you're looking for or with detectors in your mind which would sound louder if you're closer to your coveted object. but again, we have to remember where we keep things and then forget them to make life miserable.

i do not know how to overcome this problem. i do not want to give my responsibilities to others even though i know they would be much more efficient at it.
for the time being i just hope i find these set of documents that i need.
