if my place is too dirty to see where to start, it helps me to come up with a new furniture plan. this could mean moving all of the furniture or just a few key pieces; this could also mean purchasing new shelves or something of the like. if you have to move furniture or work in a new piece then you are forced to deal with the floor and surface clutter that blocks the way (not to mention anything that might be under something you are moving).
i find that once i get the ball rolling with something like this its much easier to continue and actually get the whole psychotic mess under control. when you move furniture there is an artificial feeling of greater progress which can be all the motivation i need to tackle all the other little problems in the house.
once you have your place in order you feel good. not only have you conquered a major project but your surroundings are now in harmony with the adult you are supposed to be. freshly cleaned and rearranged spaces are full of positive forward moving energy.
im more likely to shave my legs or work out or even do my homework on time if my apartment is clean and the furniture is where i like it and i dont hate my curtains.
p.s. i also bought new curtains online...
