The charm(迷人之處) of stamp collecting is collectors are free to spend as much as they want on time, money and efforts. Collectors can collect stamps whether by country, by topic, or by time period. Many years ago, it was possible to collect all kinds of stamps in the world. But with more than a half million stamps already issued worldwide, and with thousands more being released(發(fā)行) each year, that is an unrealistic dream even for the minority rich. Great rarities(稀缺) also make it impractical for anyone to gain world completeness.

This guideline may help you in whatever your collecting choices may be:

Collect what interests you. If you are interested in the colorful new stamps of some islands, collect them regardless of their future worth. If you cannot afford to get all that's available in your field, limit yourself to what interests you the most. Many fine collectors follow that path, collecting stamps just for fun. Burton, a great collector, works hard on the stamps of Panama. He delights in (喜愛) another collection simply called "Cuz I Like Them", a collection of stamps with unusual shapes.

Ernst Cohn owns one of the world' s top-grade collections of error stamps. "I am not a collector of expensive stamps, the ones only crazy people can afford and buy. I only collect inexpensive, easy-to-find stamps, which have one thing in common: a stupid error(錯誤) in their design. So far I have collected more than 1,500 stamps with at least one thing in common: 'the crazier the error, the more I like it'. "

These fine collectors mean you may do what you please, without worrying about whether anyone else collects in that way. Collecting stamps is probably the least structured hobby in the world; you can do exactly as you want.
