less clutter in your life = less clutter in your mind.
I recently bought a used backpack at a Garage Sale. It was the best mistake I made recently. It's a very nice pack at a decent price but I DIDNT NEED IT. In fact I haven't used it once since getting it.. If my old pack didnt fail recently, I probably wouldnt have been as tempted by this pack.
This mistake reminded me that I need to go lighter. I dont need to have a bunch of stuff I never use for "just in case". So thus re-inspired, Goodwill now has a bunch of my extra clothes, toys, and random, well, stuff. I havent missed any of it yet and doubt I ever will.
