I have all of the above, and I'm still a mess!!!!!!!!!
Last time I did inventory it took me 14hrs
to organize and sort all my crap. I have loads of different boxes and bags for different things when ones gets mashed up I go to another one, so on and so forth. I vowed to never let it happen again, recently it only took me 4hrs. I guess its getting better but I dont think I will ever win the battle.
I think it has to do with the person. The organized, picky type person will almost always have their stuff sorted out, and most importantly keep on top it.
