You don't have to live in some miserable minimalistic space and empty your home of all the collectible things you love just to be organized. You can enjoy your collections of favorite objects and still be organized, just don't act like a hoarder who clings to useless junk like a life raft. There are two kinds of collectors, hoarders and connoisseurs. Someone who compulsively collects objects and is constantly looking for new places to stuff their ever expanding collection because they have far more stuff than space is probably a hoarder. Connoisseurs know how to edit, curate and fine tune their collection while hoarders simple expand their collection by acquiring more stuff. Hoarders are increasing the volume of their collection, but not the overall quality. For a collector to enjoy a stylish and well organized home you need to act like a connoisseur, not a hoarder.
A true connoisseur knows that often the best way to improve a collection is to get rid of a lot of mediocre items and replace them with fewer, better quality items. This kind of trading up keeps the size of your collection under control while improving the quality of the collection. I applied this strategy to my book collection and it's working out beautifully. Over the years I have accumulated a variety of paperbacks and ordinary "bargain" books the size of a thick magazine that focus on the topic of fashion, home decor and design in general. The collection of perfectly ordinary books did not match my idea of what a truly fabulous design library would look like. My fantasy library is filled with big and beautiful glossy design books with gorgeous photography. The kind of high style books are so decorative are designed to be set out on a coffee table more for display than reference. Some of these "coffee table" books are almost big enough to serve as a coffee table if you stuck some legs on them. To create my ideal design library I occasionally get rid of what I feel are the more mediocre books to make space for the kind of books that I think of when I imagine a high class design library. What makes it easier for me to let go of various books is having a vision for what kind of collection I ultimately want to live with. Collecting with a specific intention or vision in mind makes you less susceptible to buying mediocre items just because they are a "bargain" or they fit into a general category of items you collect.
Quality, like beauty, is often in the eye of the beholder. Many cheap mass produced items (baseball cards) sell for big money simply because of the demand. By comparison many items that reflect a high level craftsmanship and better materials have a more modest dollar value on the open market. Ultimately the quality of a collection is not about it's dollar value. It's about much more subjective criteria than that. The goal of any savvy collector is not to have the biggest collection of objects, but to create the best collection. As a collector you get to create your own highly personalized definition of what elements make up your ultimate collection. Your definition of "best" objects may be based on the uniqueness of design, quality of workmanship, rarity or objects that are simply well designed practical items that are- the perfect marriage of form and function or how much certain objects give you pleasure and makes you smile.
I started collecting vintage cameras because many there was a wide selection of them that were affordable and their stylish designs appealed to me. Some of my cheaper vintage cameras cost little more than what you would pay for a disposable camera today, but I don't care about that. My criteria for buying a vintage camera is that I have to love it. I am always attracted to an interesting design. I have sold off some of my less interesting pieces for less than I paid for them, but that's how curating and editing a collection often works. You don't end up with more money when you get rid of stuff, you just end up with more free space to make room for unique pieces that come your way. Collectibles do not always increase in value over time. Buy what you love and occasionally edit out the pieces that aren't working so you have a curated collection, not a cluttered mess. Ultimately the key to a great collection is the ability to look at it like a museum curator and weed out the weak items so the stronger pieces receive the attention they deserve. It's this strategic approach that separates the connoisseurs from the hoarders.
