Pay for RAM, not speed. The speed of the computer chip does not matter; the attention-span or RAM memory does matter.
Pay for components, not cables. Buy the best components, and the cheapest cables.
Pay for speed, not channels. For cable internet, with enough speed you can watch TV channels on the internet for free.
Pay for sensor size, not pixel count. On today’s cameras you’ll have enough megapixels; better quality comes from larger sensors.
Pay for reliability, not mileage. On a car, you’ll spend more of repairs and maintaince over its lifetime than you will on a difference in gas.
Pay for comfort, not weight. A bicycle’s feather weight is moot once you add water bottle, a bag, any extra clothes you wear, while its comfort never disappears.
Pay for glass, not shutters. In professional cameras, great lenses endure, while the camera bodies change and go obsolete.
Pay for location, not square footage. A home in a good location will always retain its value. On the other hand, lots of square footage mostly means room to store stuff you don’t really need, you often have to be far from your job in order to have a huge house, and there are tons of empty McMansions sitting in the suburbs that are unable to be resold due to the housing glut.
Pay for utility, not quantity. If you’re buying kitchen implements, you’re better off buying basic tools that really work for a lot of things rather than tons of tools for specific things. You don’t need more than three knives (a paring knife, a chef’s knife, and a bread knife, along with a honing steel). You don’t need more than two pots, one saucepan, and one skillet – you can make about every dish imaginable in those four things because they’re so flexible.
Pay for hardware, not software. Most of the applications that people need for their home computer have quality free versions online. Need Office? Use OpenOffice or Google Docs. Image editing? FotoFlexer (and other such tools) do almost anything a home user would want to do.
Pay for the beans, not the coffeepot. My wife uses a cheap old coffee pot that she’s had since we were in college. The coffee you put into the pot makes all the difference, not the pot itself, according to her. A $200 coffee pot with bad coffee beans will still make you a poor drink.
Pay for speed, not size. If you’re buying a new computer and are comparing hard drives, get the faster one rather than the bigger one for home use, as it’ll speed up your computer substantially and you don’t really need another 80 GB. The fastest ones are the solid state drives, but if you’re buying a regular hard drive, get the one with the fastest RPMs. Get the smaller drive, too. You can always buy a far less expensive external USB drive for file storage if you manage to fill up your main drive.
Pay for reference, not entertainment. I only buy a book if I know I’m going to return to it again and again. For books that don’t fall into that category, I check them out at the library or swap them online.
Pay for energy efficiency, not features. When you’re buying a large appliance, the energy efficiency of the appliance outweighs virtually every feature because of the enormous amount of energy used by the appliance.
Pay for freshness, not convenience. Paying for convenience with food is usually a very poor bargain and often results in either bland food or food loaded down with so many chemicals and artificial flavorings and preservatives that you don’t even want to imagine what it’s doing to you inside. Buy fresh foods, take them home, wash them, and prepare them simply.
Pay for experiences, not things. A thing is something that takes up space in your house. An experience changes who you are as a person. One cannot be replaced, while the other can easily be replaced. Give me junky furniture and a lifetime of memories.
Pay for what you need, not what you want. This is the best tip of all. Figure out your actual needs before you ever go shopping for any item, then seek out the least expensive option that matches your needs. Your wants mostly just cost you money without giving you anything you need.
最后两条很有道理：买经历而非东西，买所需的而非所要。想买LV ， Iphone4 的少年们切记！
