I've made a concerted effort to refocus my collecting desires and pull back on some of the frivolous, for lack of a better term, spending I've fallen prey to in the past. Rather than make a bunch of small eBay purchases on things I like I'd much rather make one or two larger purchases on things I love.
This has been more difficult than it was to give up retail early on in my re-entry into the hobby, which I quickly realized ended up being nothing more than a waste of money for me and what I wanted to accomplish.
