That's awesome. When I was in the active duty Navy, I made many a port call to the Philippines, Singapore, Japan, Guam, the UK, and Afghanistan. I would never trade those experiences (even Afghanistan) for any comic book. I would not have had those opportunities before the Navy or even in the few years after transitioning into the reserves. I was fortunate to get a higher paying job than my last one, so I will have more to spend on comics if I want to.
Back to the main topic. Lately, I've been really bad about it, but I know when it's time to stop buying for a while. I agree with some of the other posts in this thread. Make a list of what you really would like to collect, and do your best to stick with it. I've found that deviating from the list is where I get into trouble. Don't just buy things to buy them. And definitely get rid of things that have no meaning for you, especially if it's just drek and cluttering up your space. I've been working on unloading stuff now and have about four long boxes of drek I intend to take to an LCS just to clear out space.
