Decluttering had a lot of unexpected changes in my thinking that I never imagined. I'm in a constant state of decluttering now! If I'm not going to use something, I get rid of it fairly quickly.

It has made my life so much easier because I no longer have to manage a ridiculous amount of stuff.

It Makes You Appreciate The Small Things In Life!

I get excited over even then smallest things. Like a new bottle of lotion, or new nail polish. Something that costs less than 5.00 can give me so much joy. Where as when I had a crazy amount of stuff, It took something really big and expensive to make me happy.
So I save money by having less. And I'm happier more of the time, Because I don't have to come up with hundreds of dollars to put a smile on my face. It just takes something small.

You Buy Only What You Need

Instead of just buying bulk amounts of random stuff, You start buying only what you need and can use now. This saves a lot of money, Sometimes buying in bulk costs more, Because you decide that you don't like the product anymore and youre stuck with 10 of them.
You buy things you need, Not things you think you need, But things you will actually use. So much of our money goes towards things we don't even like, Or will never use. They say that Americans waste half of the food they buy!

You See things Differently!

Somethings have sentimental value. While others don't have much value at all.
Sentimental value makes things complicated. YOu shouldn't get rid of all your items like that if you don't feel comfortable with it, (You usually can't replace it later). But as I own less and less, I am feeling less sentimental about my stuff.
The memories are on the inside, And no one can take them away from me, Sentimental stuff can be overwhelming and take up so much of your life. I still keep sentimental items, but I keep it to the minimum.

We own so much stuff! And many of us don't realize how things don't make us happy. Vacations and experiences can often bring more happiness While decluttering can relieve us of stress that we feel from "managing" our stuff. Decluttering is quite fulfilling.
