If you truly know what you want, certain attributes are requirements and some attributes are on the wish list. If you truly know what you want, it is often harder to find something that satisfies you, because those requirements are more specific, less generic. Finding an appropriate selection, something that meets the basic needs and still pleases you, can be very difficult, even if you take steps to ensure a wide choice. But I was raised to wait for the truly right item of quality at a higher price, rather than squander smaller amounts on something that is merely acceptable.
