If you are considered a pack rat, by yourself or anyone else, your home may be suffering from very stagnant energy. You, as a result, may also suffer from very low energy.
While I do not profess to be a specialist in feng shui, there is no doubt that a hall full of clutter does not allow the free movement of energy through the house.
Try clearing just one small space, no matter how small, and see what that does for your energy level. The table in a hallway is a great place to start since this is a classic spot for clutter to accumulate.
To help, try covering the space around the area you are clearing with a big sheet while you are clearing it. The sheet will cover up the items around and help you focus on the area you are trying to clear.
