No, not THAT one, the OTHER one.
I'm a pack rat, as I believe a lot of people are, and tend to collect everything and hold on to it for years even after finding no use for it. Sometimes my computer folders or iPhoto/iTunes libraries or my physical library or my closet get too crowded, and I have to make choices. I've gotten a lot better at this after having to sift through re-takes of audio for work, because I have to pick the best shot, all the rest goes.
Consider these points:
Make a fraction goal, i.e. if you have 100 images, decide you only need 50 and get rid of all the rest.
If you only need 1, compare all of them like a rock-paper scissors tournament. Only keep the winner.
Ask yourself, 'what do I like about this [insert object]?' Is there another piece of clothing or music or memorabilia that accomplishes that better?
If you don't love it, don't keep it.
I'm having a garage sale this weekend, and I can't tell you how satisfying it's been over the past few weeks to sift through boxes and drawers to find things to get rid of.
I've always liked this quote:
You can’t have everything.
Where would you put it?

Doesn't stop me though. I've always wanted Merlin's bag from the Sword in the Stone. Or Mary Poppin's. That would be practically perfect.
