I do the same thing - lock all the valuable cards in a large sturdy fire safe or safety deposit box, never look at them, and get bored. Similarly, I spend most of my time in an Excel spreadsheet or Access database crunching numbers like: current value vs. price paid, length of ownership vs. change in value, creating "hot & cold" lists based on price fluctuation, etc, etc. Its the geeky thing to do, but is enjoyable.

One thing that has helped is I always take clear pictures of each item, so I do spend some time reviewing the photo's and smiling!
