That's a good resolution. I hope to pull back just a little bit on the wild purchasing and shrink down some of my samples so I can wear fragrances that I already own just a little more. For example - my SotD today - it has been 1 year exactly since I last wore it. Seems a little odd to have a full bottle of something you wear once / year. But there are still so many I want... It's a tough balance to reach. Especially since my attitude about my collection goes back and forth with the tides.
I wonder if you will feel the same in a week (just your mood at the moment), or if this is more of a long term attitude shift.
Good luck either way!
