Rather than buying a bunch of the same thing with different images on it (e.g., shot glasses, keychains, etc.), I simply buy something that I find that I'll enjoy. Every time I look at that item, I will remember exactly where I bought it and the memories of the trip will be triggered. In addition, I don't find myself with 1,000 mugs that are just taking up space. So, my handmade glass miniature mantel clock will always take me back to Halifax, NS; my amber pendant and earrings will take me back to Montreal, QB; my flea art will take me back to Monterey, CA; and so on.
For me, I take greater pleasure out of the stuff I buy this way. And I don't worry about having to display everything. If I buy a pretty serving bowl, I will always smile when I use it at my table, etc.
