While cleaning up, I've always stumbled upon things that I don't wish to throw away.
Usually these are things I hold on to for some time and I just can't see my life without them.

The main problem is that I don't have enough room for them.

After doing some thinking, I've come up with the perfect solution:
I took a big box, put the things in the box and left the box in my room,
So on the one hand I couldn't see them all the time, but I know that I still have them, it's just for a while..
I continued with my life, and it seemed that I don't really need them any more, I could easily throw the box away because I'm already getting along just fine.

One important reminder: It's best not to open the box before you throw it away,
one look at what you lost and you'll be back where you started
