Downsize my interests

I've had a little scrap of paper on my computer desk for sometime, just waiting for some pondering.  "Downsize my Interests".  What can I get rid of?  Surely not sewing.  My thread collection alone is overwhelming, but I cannot part with any of it.  I could part with some of the empty spools!  I did make the decision a long time ago to keep only the wood spools.  Plastic goes into the recycle bin (unless it has an unusual bottom that can be used for stamping...)  Part of the minimalist approach is to get rid of things rather than organize them.  Not today...  I shall go right now and organize my threads.
