Freedom, I have a little treasure chest (jewelry box), a photo storage box and an actual pencil box filled with pens, highlighters, art pencils and markers; an entire cubby filled with pretty little notebooks and journals. (This doesn't count the notebooks, crayons and markers that I've bought for DS.)
I think I was a scribe or writer in a previous life. I love the feel of some pens on some types of paper. The ones I don't like come to work with me to be put next to the fax machine and front desk. Free to a good home.
In high school I found the perfect pen. Saved up (yep, you read that right - saved up - for a pen) from a summer job to buy it, went back to the store - and it was gone - out of stock - discontinued.
