I decluttered for almost a year. Every day for 15 minutes, I went into a different room and went through a small section and threw out everything I could. After I got my life together, I started donating. I would call up Am Vets and arrange a pick up date for a donation (they'll come to your house and pick it up from the porch). For the month before the pick up date, I would fill up bags and leave them in the dining room until pick up date. I've probably given away half of my belongings in the last year and it felt great!
Once your done decluttering, you're left with a very small amount of stuff that you actually need. Now is the time to start organizing. You have two options, you can head to the container store or Bed Bath and Beyond and buy gorgeous fabric covered containers to put your things away or you can head to the Dollar Tree and pick up a bunch of really well made containers.
Here are a few examples of how I use Dollar Tree containers (each 1.00!) in our house:
All of our office supplies are separated into the green containers onto the top shelves and labeled. The green containers are available at Dollar Tree for one dollar apiece. They have these in several colors and sizes.
We upgraded our previous cardboard snack box to Dollar Tree's stackable bins. They have these in several colors.
These bins are pretty sturdy and well worth the dollar paid. I like them better than similar containers found at Walmart.
